This is the site I play on, but this cheating happened on the high stakes no limit cash games (I only play tournaments online). Not sure of any of you heard but about a year ago Absolute Poker was involved in this exact same cheating scandal. Basically the old owners (Founders) of the sites had access to software showing other players hole cards. It's interesting to think about how these guys probably stole millions and millions of unsuspecting dollars before being caught, and with seemingly no law to govern what was going on. This is a perfect example of how the US is going backwards by trying to ban online poker, instead of regulate it. Interesting reading.
