Facebook, Zynga Users Try to Revive Privacy Claims on Appeal

Facebook Inc. and Zynga Inc. should be ordered to face claims that users’ identities and activities on the social networking platforms were disclosed to third parties without their consent, plaintiffs’ lawyers told a federal appeals court panel.

The plaintiffs are asking the U.S. Court of Appeals in San Francisco to revive complaints filed in 2010 and dismissed the following year. Some of their claims are are based on privacy practices and policies that the companies have since changed, their lawyers said.
