Digital Daredevil Behind Megaupload Has a New Venture

AUCKLAND — At 6:48 a.m. Sunday, the Internet tycoon Kim Dotcom opened his new file-storage Web site to the public — one year to the minute after the police raided the mansion he rents in New Zealand.

The raid was part of a coordinated operation with the F.B.I. that also shut down Megaupload, the file-sharing business he had founded.

Mr. Dotcom faces charges in the United States of pirating copyrighted material and money laundering and is awaiting an extradition hearing in New Zealand. But on Sunday, his focus was on the new site, which was already straining under heavy traffic within two hours of its introduction. In the first 14 hours of the site’s operation, more than half a million people registered to use it, Mr. Dotcom said.

“This should not be seen as the mocking of any government or Hollywood,” Mr. Dotcom, 39, said Sunday at a news conference at the Auckland mansion. “This is us being innovators and executing our right to run a business.”

The event marking the introduction of Mega, held at the same property that had been raided by the police, was designed to be a spectacle. As Mr. Dotcom addressed a large crowd of journalists and guests, actors dressed as armed police officers rappelled down the sloping roof of the main house and shouted that all those present would be detained. A helicopter emblazoned with “F.B.I.” hovered overhead.

Mr. Dotcom, a German citizen and permanent resident of New Zealand who was born Kim Schmitz, was arrested Jan. 20, 2012. During the raid on his home that day, the police seized vehicles worth about 6 million New Zealand dollars, or $5 million, and froze about 11 million dollars in bank accounts, according to a news release issued at the time.

Over the past year, Mr. Dotcom has become an ever-prominent figure in New Zealand as the legal and political saga surrounding his case has played out in the public sphere.

In June, a High Court judge ruled that the police had used the wrong type of search warrants to enter Mr. Dotcom’s property, meaning that the raid had been illegal. In September, Prime Minister John Key of New Zealand apologized to Mr. Dotcom after it was disclosed that the country’s intelligence agency had acted illegally by spying on him, even though he holds a permanent resident’s visa.

Mega, Mr. Dotcom’s new Web site, is a file-storage and sharing system that encrypts files on one’s computer before they are uploaded to the site’s servers. Files can then be downloaded and decrypted. This means that files on Mega’s servers cannot be read by anyone, including by the company itself, without the user’s decryption key.

The allegation that Mr. Dotcom’s previous venture, Megaupload, knew its users were illegally uploading copyrighted material — and indeed sought to encourage the practice — is a crucial part of the U.S. Department of Justice’s indictment against the site and those who operated it.

In contrast, the new site appears to distance Mega intentionally from any legal responsibility for the content on its servers, although the terms and conditions of the site do explicitly forbid uploading copyrighted material.

“What he’s trying to do is give himself a second-string argument,” Charles Alexander, a lawyer in Sydney who specializes in intellectual property law, told The Associated Press. “‘Even if I was wrong before, this one’s all right because how can I control something if I don’t know that it’s there?”’ he imagined the new company thinking. “I can understand the argument; whether it would be successful or not is another matter.”

U.S. prosecutors declined to comment on the new site, The A.P. reported, referring only to a court document that cites promises Mr. Dotcom made while seeking bail, including one that he would not start a Megaupload-style business until the criminal case was resolved.

“Legally it’s probably the most scrutinized Internet start-up in history,” Mr. Dotcom said. “Every pixel on the site has been checked for, you know, all kinds of illegal — potential legal challenges. We have a great team of very talented lawyers that are experts in intellectual property and Internet law, and they have worked together with us to create Mega.”

The Motion Picture Association of America, which has filed complaints about alleged copyright infringement by Megaupload, told The A.P. that it was skeptical that Mr. Dotcom’s new site was harmless. “We are still reviewing how this new project will operate, but we do know that Kim Dotcom has built his career and his fortune on stealing creative works,” it said in a news release.

The Mega site offers 50 gigabytes of storage free; additional storage and bandwidth can be purchased at three tiers of monthly fees.

Well: Holly the Cat's Incredible Journey

Nobody knows how it happened: an indoor housecat who got lost on a family excursion managing, after two months and about 200 miles, to return to her hometown.

Even scientists are baffled by how Holly, a 4-year-old tortoiseshell who in early November became separated from Jacob and Bonnie Richter at an R.V. rally in Daytona Beach, Fla., appeared on New Year’s Eve — staggering, weak and emaciated — in a backyard about a mile from the Richter’s house in West Palm Beach.

“Are you sure it’s the same cat?” wondered John Bradshaw, director of the University of Bristol’s Anthrozoology Institute. In other cases, he has suspected, “the cats are just strays, and the people have got kind of a mental justification for expecting it to be the same cat.”

But Holly not only had distinctive black-and-brown harlequin patterns on her fur, but also an implanted microchip to identify her.

“I really believe these stories, but they’re just hard to explain,” said Marc Bekoff, a behavioral ecologist at the University of Colorado. “Maybe being street-smart, maybe reading animal cues, maybe being able to read cars, maybe being a good hunter. I have no data for this.”

There is, in fact, little scientific dogma on cat navigation. Migratory animals like birds, turtles and insects have been studied more closely, and use magnetic fields, olfactory cues, or orientation by the sun.

Scientists say it is more common, although still rare, to hear of dogs returning home, perhaps suggesting, Dr. Bradshaw said, that they have inherited wolves’ ability to navigate using magnetic clues. But it’s also possible that dogs get taken on more family trips, and that lost dogs are more easily noticed or helped by people along the way.

Cats navigate well around familiar landscapes, memorizing locations by sight and smell, and easily figuring out shortcuts, Dr. Bradshaw said.

Strange, faraway locations would seem problematic, although he and Patrick Bateson, a behavioral biologist at Cambridge University, say that cats can sense smells across long distances. “Let’s say they associate the smell of pine with wind coming from the north, so they move in a southerly direction,” Dr. Bateson said.

Peter Borchelt, a New York animal behaviorist, wondered if Holly followed the Florida coast by sight or sound, tracking Interstate 95 and deciding to “keep that to the right and keep the ocean to the left.”

But, he said, “nobody’s going to do an experiment and take a bunch of cats in different directions and see which ones get home.”

The closest, said Roger Tabor, a British cat biologist, may have been a 1954 study in Germany which cats placed in a covered circular maze with exits every 15 degrees most often exited in the direction of their homes, but more reliably if their homes were less than five kilometers away.

New research by the National Geographic and University of Georgia’s Kitty Cams Project, using video footage from 55 pet cats wearing video cameras on their collars, suggests cat behavior is exceedingly complex.

For example, the Kitty Cams study found that four of the cats were two-timing their owners, visiting other homes for food and affection. Not every cat, it seems, shares Holly’s loyalty.

KittyCams also showed most of the cats engaging in risky behavior, including crossing roads and “eating and drinking substances away from home,” risks Holly undoubtedly experienced and seems lucky to have survived.

But there have been other cats who made unexpected comebacks.

“It’s actually happened to me,” said Jackson Galaxy, a cat behaviorist who hosts “My Cat From Hell” on Animal Planet. While living in Boulder, Colo., he moved across town, whereupon his indoor cat, Rabbi, fled and appeared 10 days later at the previous house, “walking five miles through an area he had never been before,” Mr. Galaxy said.

Professor Tabor cited longer-distance reports he considered credible: Murka, a tortoiseshell in Russia, traveling about 325 miles home to Moscow from her owner’s mother’s house in Voronezh in 1989; Ninja, who returned to Farmington, Utah, in 1997, a year after her family moved from there to Mill Creek, Wash.; and Howie, an indoor Persian cat in Australia who in 1978 ran away from relatives his vacationing family left him with and eventually traveled 1,000 miles to his family’s home.

Professor Tabor also said a Siamese in the English village of Black Notley repeatedly hopped a train, disembarked at White Notley, and walked several miles back to Black Notley.

Still, explaining such journeys is not black and white.

In the Florida case, one glimpse through the factual fog comes on the little cat’s feet. While Dr. Bradshaw speculated Holly might have gotten a lift, perhaps sneaking under the hood of a truck heading down I-95, her paws suggest she was not driven all the way, nor did Holly go lightly.

“Her pads on her feet were bleeding,” Ms. Richter said. “Her claws are worn weird. The front ones are really sharp, the back ones worn down to nothing.”

Scientists say that is consistent with a long walk, since back feet provide propulsion, while front claws engage in activities like tearing. The Richters also said Holly had gone from 13.5 to 7 pounds.

Holly hardly seemed an adventurous wanderer, though her background might have given her a genetic advantage. Her mother was a feral cat roaming the Richters’ mobile home park, and Holly was born inside somebody’s air-conditioner, Ms. Richter said. When, at about six weeks old, Holly padded into their carport and jumped into the lap of Mr. Richter’s mother, there were “scars on her belly from when the air conditioner was turned on,” Ms. Richter said.

Scientists say that such early experience was too brief to explain how Holly might have been comfortable in the wild — after all, she spent most of her life as an indoor cat, except for occasionally running outside to chase lizards. But it might imply innate personality traits like nimbleness or toughness.

“You’ve got these real variations in temperament,” Dr. Bekoff said. “Fish can by shy or bold; there seem to be shy and bold spiders. This cat, it could be she has the personality of a survivor.”

He said being an indoor cat would not extinguish survivalist behaviors, like hunting mice or being aware of the sun’s orientation.

The Richters — Bonnie, 63, a retired nurse, and Jacob, 70, a retired airline mechanics’ supervisor and accomplished bowler — began traveling with Holly only last year, and she easily tolerated a hotel, a cabin or the R.V.

But during the Good Sam R.V. Rally in Daytona, when they were camping near the speedway with 3,000 other motor homes, Holly bolted when Ms. Richter’s mother opened the door one night. Fireworks the next day may have further spooked her, and, after searching for days, alerting animal agencies and posting fliers, the Richters returned home catless.

Two weeks later, an animal rescue worker called the Richters to say a cat resembling Holly had been spotted eating behind the Daytona franchise of Hooters, where employees put out food for feral cats.

Then, on New Year’s Eve, Barb Mazzola, a 52-year-old university executive assistant, noticed a cat “barely standing” in her backyard in West Palm Beach, struggling even to meow. Over six days, Ms. Mazzola and her children cared for the cat, putting out food, including special milk for cats, and eventually the cat came inside.

They named her Cosette after the orphan in Les Misérables, and took her to a veterinarian, Dr. Sara Beg at Paws2Help. Dr. Beg said the cat was underweight and dehydrated, had “back claws and nail beds worn down, probably from all that walking on pavement,” but was “bright and alert” and had no parasites, heartworm or viruses. “She was hesitant and scared around people she didn’t know, so I don’t think she went up to people and got a lift,” Dr. Beg said. “I think she made the journey on her own.”

At Paws2Help, Ms. Mazzola said, “I almost didn’t want to ask, because I wanted to keep her, but I said, ‘Just check and make sure she doesn’t have a microchip.’” When told the cat did, “I just cried.”

The Richters cried, too upon seeing Holly, who instantly relaxed when placed on Mr. Richter’s shoulder. Re-entry is proceeding well, but the mystery persists.

“We haven’t the slightest idea how they do this,” Mr. Galaxy said. “Anybody who says they do is lying, and, if you find it, please God, tell me what it is.”

N.T.S.B. Rules Out a Cause for Battery Fire on 787 Dreamliner

TOKYO — The National Transportation Safety Board has ruled out excess voltage as the cause of a battery fire on the Boeing 787 Dreamliner jet operated by Japan Airlines at Boston’s Logan Airport this month, the agency said on Sunday.

Last week, governments across the world grounded the Dreamliner jet after a problem with a lithium-ion battery on a second 787 plane, flown by All Nippon Airways forced the jet to make an emergency landing in western Japan.

The agency said in a statement forwarded by a Boeing Japan representative that examination of the flight recorder data from the JAL B-787 airplane indicated that the battery in the auxiliary power unit “did not exceed its designed voltage of 32 volts.”

On Friday, a Japanese safety official told reporters that excessive electricity may have overheated the battery in the ANA-owned Dreamliner, which was forced to make an emergency landing at Japan’s Takamatsu airport last week.

American investigators have examined the lithium-ion battery that powered the auxiliary unit, where the battery fire started in the JAL plane, as well as several other components removed from the airplane, including wire bundles and battery management circuit boards, the safety agency statement said.

On Tuesday, the investigating group will convene in Arizona to test and examine the battery charger and download nonvolatile memory from the controller of the auxiliary power unit, it added.

The GS Yuasa Corporation of Japan makes the batteries for the Dreamliner, while Thales of France makes the control systems for the battery.

IHT Rendezvous: Can Armstrong be Redeemed? How About Galliano?

LONDON — While Lance Armstrong was (not quite) baring his soul to Oprah this week, a very different celebrity, the disgraced London fashion designer John Galliano, was taking a small step on the path to redemption.

Two years after he was ousted from Dior in the wake of his arrest for a drunken, anti-Semitic rant in a Paris bar, Mr. Galliano is to make a modest comeback at the New York design studio of Oscar de La Renta.

As Eric Wilson writes over at On the Runway, many had speculated that the man described as “the prince of romantic glamor” would never work in the fashion industry again after his downfall in 2011.

However, with the support of fashion luminaries such as Anna Wintour and Grace Coddington of Vogue, he appears set for rehabilitation.

“As far as a comeback strategy, working for Mr. de la Renta in a casual capacity, practically an intern, is, in effect, a way of testing the waters,” Eric writes.

The downfall of the Gibraltar-born, London-raised designer came after two patrons of a bar in the Marais district of Paris accused him of making an anti-Semitic slur.

An online video later surfaced that showed a previous incident in which a bleary Mr. Galliano told fellow customers in the same bar, “I love Hitler” and “people like you would be dead” and “your mothers, your forefathers” would all be “gassed.”

All the more surprising, then, that among those who welcomed the 52-year-old designer’s return was Abraham H. Foxman of the Anti-Defamation league.

The head of the American anti-Semitism watchdog group said on Friday, “Mr. Galliano has worked arduously in changing his worldview and dedicated a significant amount of time to researching, reading, and learning about the evils of anti-Semitism and bigotry.”

The A.D.L. had met the designer on numerous occasions and hoped to work with him in the future as a spokesman against bigotry.

A Paris court fined Mr. Galliano €6,000, or $8,000, for racial insults after he offered his apologies, and last year President François Hollande stripped him of the Légion d’Honneur that he was awarded in 2009.

The designer’s behavior was widely blamed on drug and alcohol addiction, which he’s sought treatment for over the last two years.

“Under intense pressure to produce at least eight full collections a year, Galliano — like so many other artists — reached for sustenance and oblivion,” Suzy Menkes, the IHT’s fashion editor, wrote in November.

Another celebrity who has admitted to turning to drugs, but for very different reasons, is Lance Armstrong, the disgraced American cycling superstar who came clean to Oprah Winfrey this week.

Summing up the response among cycling and anti-doping officials, my colleague Ian Austen wrote: “Many characterized Armstrong’s interview with Oprah Winfrey as being more self-serving than revelatory.”

Has Mr. Armstrong done enough to pave the way for an eventual comeback or were his television appearances indeed self-serving? And what about Mr. Galliano? Should his repentance for his unpardonable remarks lead to a second chance at success? Does either celebrity — or both — deserve redemption? Tell us what you think.

With Graph Search, Facebook Bets on More Sharing

SAN FRANCISCO — Facebook’s greatest triumph has been to persuade a seventh of the world’s population to share their personal lives online.

Now the social network is taking on its archrival, Google, with a search tool to mine that personal information, just as people are growing more cautious about sharing on the Internet and even occasionally removing what they have already put up.

Whether Facebook’s more than one billion users will continue to divulge even more private details will determine whether so-called social search is the next step in how we navigate the online world. It will also determine whether Facebook has found a business model that will make it a lot of money.

“There’s a big potential upside for both Facebook and users, but getting people to change their behaviors in relation to what they share will not be easy,” said Andrew T. Stephen, who teaches marketing at the University of Pittsburgh and studies consumer behavior on online social networks.

This week, Facebook unveiled its search tool, which it calls graph search, a reference to the network of friends its users have created. The company’s algorithms will filter search results for each person, ranking the friends and brands that it thinks a user would trust the most. At first, it will mine users’ interests, photos, check-ins and “likes,” but later it will search through other information, including status updates.

“While the usefulness of graph search increases as people share more about their favorite restaurants, music and other interests, the product doesn’t hinge on this,” a Facebook spokesman, Jonathan Thaw, said.

Nevertheless, the company engineers who created the tool — former Google employees — say that the project will not reach its full potential if Facebook data is “sparse,” as they call it. But the company is confident people will share more data, be it the movies they watch, the dentists they trust or the meals that make their mouths water.

The things people declare on Facebook will be useful, when someone searches for those interests, Tom Stocky, one of the creators of Facebook search, said in an interview this week. Conversely, by liking more things, he said, people will become more useful in the eyes of their friends.

“You might be inclined to ‘like’ what you like so when your friends search, they’ll find it,” he said. “I probably would never have liked my dentist on Facebook before, but now I do because it’s a way of letting my friends know.”

Mr. Stocky offered these examples of how more information may be desirable: A single man may want to be discovered when a friend of a friend is searching for eligible bachelors in San Francisco or a restaurant that stays open late may want to be found by a night owl.

“People have shared all this great stuff on Facebook,” Mr. Stocky said. “It’s latent value. We wanted a way to unlock that.”

Independent studies suggest that Facebook users are becoming more careful about how much they reveal online, especially since educators and employers typically scour Facebook profiles.

A Northwestern University survey of 500 young adults in the summer of 2012 found that the majority avoided posting status updates because they were concerned about who would see them. The study also found that many had deleted or blocked contacts from seeing their profiles and nearly two-thirds had untagged themselves from a photo, post or check-in.

“These behavioral patterns seem to suggest that many young adults are less keen on sharing at least certain details about their lives rather than more,” said Eszter Hargittai, an associate professor of communication studies at Northwestern, who led the yet unpublished study among men and women aged 21 and 22.

Also last year, the Pew Internet Center found that social network users, including those on Facebook, were more aggressively pruning their profiles — untagging photos, removing friends and deleting comments.

Business Briefing | Medicine: F.D.A. Clears Botox to Help Bladder Control

Botox, the wrinkle treatment made by Allergan, has been approved to treat adults with overactive bladders who cannot tolerate or were not helped by other drugs, the Food and Drug Administration said on Friday. Botox injected into the bladder muscle causes the bladder to relax, increasing its storage capacity. “Clinical studies have demonstrated Botox’s ability to significantly reduce the frequency of urinary incontinence,” Dr. Hylton V. Joffe, director of the F.D.A.’s reproductive and urologic products division, said in a statement. “Today’s approval provides an important additional treatment option for patients with overactive bladder, a condition that affects an estimated 33 million men and women in the United States.”

Analysis: Amid Tears Lance Armstrong Leaves Unanswered Questions in Oprah Winfrey Interview

In an extensive interview with Oprah Winfrey that was shown over two nights, Lance Armstrong admitted publicly for the first time that he doped throughout his cycling career. He revealed that all seven of his Tour de France victories were fueled by doping, that he never felt bad about cheating, and that he had covered up a positive drug test at the 1999 Tour with a backdated doctor’s prescription for banned cortisone.

Armstrong, the once defiant cyclist, also became choked up when he discussed how he told his oldest child that the rumors about Armstrong’s doping were true.

Even with all that, the interview will most likely be remembered for what it was missing.

Armstrong had not subjected himself to questioning from anyone in the news media since United States antidoping officials laid out their case against him in October. He chose not to appeal their ruling, leaving him with a lifetime ban from Olympic sports.

He personally chose Winfrey for his big reveal, and it went predictably. Winfrey allowed him to share his thoughts and elicited emotions from him, but she consistently failed to ask critical follow-up questions that would have addressed the most vexing aspects of Armstrong’s deception.

She did not press him on who helped him dope or cover up his drug use for more than a decade. Nor did she ask him why he chose to take banned performance-enhancing substances even after cancer had threatened his life.

Winfrey also did not push him to answer whether he had admitted to doctors in an Indianapolis hospital in 1996 that he had used performance-enhancing drugs, a confession a former teammate and his wife claimed they overheard that day. To get to the bottom of his deceit, antidoping officials said, Armstrong has to be willing to provide more details.

“He spoke to a talk-show host,” David Howman, the director general of the World Anti-Doping Agency, said from Montreal on Friday. “I don’t think any of it amounted to assistance to the antidoping community, let alone substantial assistance. You bundle it all up and say, ‘So what?’

Jeffrey M. Tillotson, the lawyer for an insurance company that unsuccessfully withheld a $5 million bonus from Armstrong on the basis that he had cheated to win the Tour de France in 2004, said his client would make a decision over the weekend about whether to sue Armstrong. If it proceeds, the company, SCA Promotions, will seek $12 million, the total it paid Armstrong in bonuses and legal fees.

“It seemed to us that he was more sorry that he had been caught than for what he had done,” Tillotson said. “If he’s serious about rehabbing himself, he needs to start making amends to the people he bullied and vilified, and he needs to start paying money back.”

Armstrong, who said he once believed himself to be invincible, explained in the portion of the interview broadcast Friday night that he started to take steps toward redemption last month. Then, after dozens of questions had already been lobbed his way, he became emotional when he described how he told his 13-year-old son, Luke, that yes, his father had cheated by doping. That talk happened last month over the holidays, Armstrong said as he fought back tears.

“I said, listen, there’s been a lot of questions about your dad, my career, whether I doped or did not dope, and I’ve always denied, I’ve always been ruthless and defiant about that, which is probably why you trusted me, which makes it even sicker,” Armstrong said he told his son, the oldest of his five children. “I want you to know it’s true.”

At times, Winfrey’s interview seemed more like a therapy session than an inquisition, with Armstrong admitting that he was narcissistic and had been in therapy — and that he should be in therapy regularly because his life was so complicated.

In the end, the interview most likely accomplished what Armstrong had hoped: it was the vehicle through which he admitted to the public that he had cheated by doping, which he had lied about for more than a decade. But his answers were just the first step to clawing back his once stellar reputation.

On Friday, Armstrong appeared more contrite than he had during the part of the interview that was shown Thursday, yet he still insisted that he was clean when he made his comeback to cycling in 2009 after a brief retirement, an assertion the United States Anti-Doping Agency said was untrue. He also implied that his lifetime ban from all Olympic sports was unfair because some of his former teammates who testified about their doping and the doping on Armstrong’s teams received only six-month bans.

Richard Pound, the founding chairman of WADA and a member of the International Olympic Committee, said he was unmoved by Armstrong’s televised mea culpa.

“If what he’s looking for is some kind of reconstruction of his image, instead of providing entertainment with Oprah Winfrey, he’s got a long way to go,” Pound said Friday from his Montreal office.

Armstrong acknowledged to Winfrey during Friday’s broadcast that he has a long way to go before winning back the public’s trust. He said he understood why people recently turned on him because they felt angry and betrayed.

“I lied to you and I’m sorry,” he said before acknowledging that he might have lost many of his supporters for good. “I am committed to spending as long as I have to to make amends, knowing full well that I won’t get very many back.”

Armstrong also said that the scandal has cost him $75 million in lost sponsors, all of whom abandoned him last fall after Usada made public 1,000 pages of evidence that Armstrong had doped.

“In a way, I just assumed we would get to that point,” he said of his sponsors’ leaving. “The story was getting out of control.”

In closing her interview, Winfrey asked Armstrong a question that left him perplexed.

“Will you rise again?” she said.

Armstrong said: “I don’t know. I don’t know. I don’t know what’s out there.”

Then, as the interview drew to a close, Armstrong said: “The ultimate crime is the betrayal of these people that supported me and believed in me.”

Tell-All on the Internet Fells Chinese Official

BEIJING — Viewed through the lens of the Marxist tenets he so arduously promoted, Yi Junqing’s transactional relationship with an ambitious female researcher would have probably fallen into the category of exploitive.

Mr. Yi, 54, an impish scholar who is China’s top guardian of Communist literature, is said to have provided the woman with a fellowship at his research institute in exchange for $1,600. The sex and jewelry came later.

The allegations came to light last month after the woman, Chang Yan, 34, posted online a self-indulgent and occasionally scintillating diary that recounted a yearlong affair between the two married scholars. A few days later, Ms. Chang tried to retract her sprawling tell-all but the damage was done.

On Thursday Mr. Yi, director of the Central Compilation and Translation Bureau, was dismissed from his job. Xinhua, the state news agency, kept its dispatch brief and clean: Mr. Yi, it said, was let go over “lifestyle issues.”

In a season when dozens of ethically challenged Chinese officials have been felled by their lust for women, money and luxury timepieces, the downfall of Mr. Yi prompted a hearty round of snickering and schadenfreude, and not only because his vice minister rank made him one of the more senior party members to lose his job over official malfeasance.

“People have come to treat such news as entertainment, but that’s only because we feel so helpless,” said Zhu Ruifeng, a muckraking journalist who specializes in the misdeeds of Chinese officials.

Mr. Yi’s main job, after all, was to propagate the leftist and often puritanical teachings of Mao Zedong and other Communist luminaries at a time when many Chinese have grown disenchanted by the seeming lack of rectitude among their leaders. The headline in the Qianjiang Evening News of Hangzhou seemed to sum up the public’s disgust: “Mouthful of Marxism-Leninism, Mind Full of Filth and Vice.” The commentary went on to lambast Mr. Yi for selling positions at his institute, which has a staff of nearly 300 and is charged with translating Marxist tracts into Chinese and Chinese government documents into a number of foreign languages.

Even if party leaders ultimately tossed Mr. Yi overboard, it was the Internet that sealed his fate. Over the past two months, a parade of corrupt officials have been exposed by enterprising journalists, anonymous tipsters — or in Mr. Yi’s case, jilted lovers.

Recent cases include the relatives of a housing official in Henan Province who had collected 31 properties and a deputy mayor in Guangdong Province who was fired and placed under investigation after his cozy ties to a local drug gang were publicly revealed by a disgruntled underling.

Given China’s normally tight censorship restrictions, some analysts have suggested that the spate of scandals appearing online are a sign the new leadership is committed to fighting corruption in the party. During his inaugural address in November, Xi Jinping, the new Communist Party chief and incoming president, warned that unchecked graft threatened to destroy the party.

Indeed, Xinhua, on its microblog account, tried to put a positive spin on the latest scandal, saying “The resolute management of problematic officials shows the determination of the party’s fight against corruption.”

Judging from the deluge of biting commentary on Sina Weibo, the Chinese equivalent of Twitter, not many people were convinced. “The shameful step-down of this minister-level official once again proves the Internet wisdom: rumors are but prophesies,” Xue Manzi, a well-followed businessman, wrote on his microblog.

When it comes to Chinese-style scandal, Mr. Yi’s transgressions — at least those alleged by his former lover — are not particularly spectacular. He seems to have had a fondness for sushi and sake, and for lunchtime tête-à-têtes at a Beijing hotel with Ms. Chang — 17 of them, by her count.

She described a man who enjoyed talking politics, but also about his own achievements. “I am quite talented after all,” he supposedly said after recounting the favorable impression he made on Mr. Xi, the party chief. Ms. Chang does not exactly come off as a naïf. After bribing him with Swarovski baubles, a bottle of Boss cologne and an additional $8,000, she said she grew angry when Mr. Yi failed to secure her a permanent position at his institute. She was also not pleased to learn he had other lovers. In the end, she admits she tried to blackmail him, demanding nearly $50,000 to leave him alone.

After the diary’s release, Ms. Chang tried to backpedal, saying she was depressed and nearly delusional from working too much when she wrote its 100,000 characters. “In my spare time I put together a work of fiction,” she said.
