Facebook Inc. (FB), the social network operator whose shares began trading today, was sued for $15 billion in an amended complaint by subscribers who claim the company invaded their privacy by tracking their Internet use.
In the complaint filed yesterday in federal court in San Jose, California, the plaintiffs say Facebook improperly tracked users even after they logged out. Twenty-one cases making similar claims have been consolidated before the court. The latest filing seeks to proceed on behalf of U.S. residents who subscribed to Facebook from May 2010 to September 2011.
Facebook, which sold stock in an initial public offering valuing the company at about $104 billion, has been scrutinized by regulators in the U.S. and Europe over how it protects users’ private information. Last year, a German data-protection agency said it may fine the Menlo Park, California-based company over facial-recognition software used for tagging photos.
