Facebook - Farmville and Mafia War member IDs leaked

I've always cautioned friends to avoid these types of games, (e.g., may pick up malicious strangers as "friends" who can misuse sensitive information, it may annoy some FB users, etc).  This may not be a significant issue, as social networking is a wide-open and non-private environment setting. Still if promises of privacy were broken, it'll be interesting to see if anything becomes of it.

QUOTE: 218 million “class members” probably won’t settle for Farmville dollars.  A suit has been filed in U.S. District Court in San Francisco on behalf of a Minnesota woman charging game maker Zynga with leaking the personal information of 218 million Facebook members in violation of federal law. The suit seeks class action status.

The lawsuit alleges that Zynga, maker of six of the top 10 Facebook games, collected and shared the IDs of 218 million users, in violation of federal law and terms of service. It seeks unspecified monetary damages and an injunction preventing the alleged practice from continuing. The suit was filed in US District Court in San Francisco on behalf of Nancy Graf of St. Paul, Minnesota. It seeks class action status so other Facebook users may also be represented.

The action follows an investigation by The Wall Street Journal that found that a large number of Facebook apps, including all of the top 10, transmitted the unique user IDs of those who ran them to outside companies. Zynga – maker of games such as Farmville, Mafia Wars, and Cafe World – was found to be “transmitting personal information about a user's friends to outside companies,” the paper reported
