Zynga and Facebook have both been named in a class action lawsuit following the alleged use of advertising which users say was false and misleading.
Lead by Sacramento-based law firm Kershaw, Cutter and Ratinoff, is seeking upwards of USD 5 million in damages, claiming that "over the past four years, Zynga and Facebook have generated enormous profits through these false and misleading special offers."

"...Facebook is fully aware of the false and misleading nature of the advertising promulgated through Zynga's applications and despite this, it actively engages in promoting Zynga's game to the public," reads the suit, published by Valleywag.

Zynga CEO Mark Pincus blog says that the company has been unable to control the ads in its games because they're managed by partner companies, but has now removed them.

"We recognise it is our responsibility to ensure that offers which generate a bad user experience are not shown with any of our games. Therefore, we are removing all CPA offers across Zynga games until we can control their inclusion and presentation ourselves."

A video of Pincus admitting, "I did every horrible thing in the book just to get revenues," is expected to be used a courtroom evidence.
