A group of 21 Facebook users who claim to have had their privacy violated by Facebook's online tracking are seeking $15 billion in damages, Bloomberg reports.
The suit alleges that Facebook improperly tracked the online activities of the social network's 800 million users between May 2010 and September 2011.
Attorney David Straite told Bloomberg that he was bringing a "groundbreaking digital-privacy rights case that could have wide and significant legal and business implications." Facebook plans to fight the case.
The news broke on the day of Facebook's rather unspectacular initial public offering, As of this writing, shares were trading at just a few cents over the IPO price of $38 per share.
