Zynga has taken hacker Ashley Mitchell to court, where he has admitted to breaking into the controlled servers of Zynga Poker.  He posed as a game administrator over several months in 2009, acquiring 400 billion chips illegally and selling about one-third.

While the virtual poker chips were worth about $12 million, he only generated about $85,500 from their sale. Mitchell pleaded guilty to five charges brought under the Computer Misuse Act and the Proceeds from Crime Act at the Exeter Crown Court.
