We have done an extensive research into the claims that have been brought to our attention. While we are continuing to do a thorough and exhaustive investigation, we have yet to find any evidence of wrong doing.
When you are logged in and playing your game client only receives data regarding your hole cards. As a result, it is impossible for a player to have information regarding any other player's hole cards. There are no "superuser" accounts that enable players to see other players' hole cards.
Despite our confidence in the security of our systems, we researched hands involving accounts that were mentioned in the online forum posts over the weekend and did not find any incidence of cheating by the accounts in question. Results mentioned in the forums were over a small sample of hands, and we have researched these hands as well as numerous other hands involving these players and have found that the pattern of play of the players did not lend credibility to the claim that the players knew the cards of other players at the table. Certainly there were hands that were played poorly, from a poker strategy perspective, and where these players received a fortunate result. However, a longer term review has shown that similar playing strategies have not resulted in the same results as these players achieved in the small sample of hands mentioned in the online discussion.
