Basically, there has been a cheating scandal at Absolute Poker. Players in high stakes limit cash games, NL cash games, and tournaments lost hundreds of thousands of dollars to cheaters who could see their hole cards. Apparently, it was done by insiders.
Absolute Poker has repeatedly lied about the cheating and threatened legal action against those disparaging it, but they finally admitted to some of the cheating and have been compensating the victims. The full scope of the cheating is not yet known.
