Facebook has been【C1】______with fire and has got its fingers burned, again. On November 29

th America s Federal Trade Commission(FTC)announced that it had reached a【C2】______settlement with the giant social network over【C3】______that it had misled people about its use of their personal data. The details of the settlement make clear that Facebook, which【C4】______over 800 m users, betrayed its users trust. It is also notable because it appears to be part of a broader【C5】______by the FTC to craft a new privacy framework to deal with the rapid【C6】______of social networks in America. The regulator s findings come at a【C7】______moment for Facebook, which is said to be preparing for an initial public offering next year that could value it at around $100 billion. To【C8】______the way for its listing, the firm first needs to resolve its privacy【C9】______with regulators in America and Europe,【C10】______its willingness to negotiate the settlement【C11】______this week. Announcing the agreement, the FTC said it had found a number of cases where Facebook had made claims that were " unfair and deceptive, and【C12】______federal law". For instance, it【C13】______personally identifiable information to advertisers, and it failed to keep a promise to make photos and videos on deleted accounts【C14】______. The settlement does not【C15】______an admission by Facebook that it has broken the law, but it deeply【C16】______the company nonetheless. In a blog post published the same day, Mark Zuckerberg, Facebook s boss, tried to【C17】______the impact of the deal. First he claimed that " a small number of high-profile mistakes" were【C18】______the social networks "good history" on privacy. The FTC is not relying on Facebook to police itself. Among other things, the company will now have to seek consumers approval before it changes the way it shares their data. And it has agreed to an independent privacy audit every two years for the next 20 years. There is a clear pattern here. In separate cases over the past couple of years the FTC has insisted that Twitter and Google accept regular【C19】______audits, too, after each firm was accused of violating its customers privacy. The intent seems to be to create a regulatory regime that is tighter than the status quo,【C20】______one that still gives social networks plenty of room to innovate.
