Got this email from PokerStars today. I'm amazed by this. Haven't been able to check the amount of my credit yet, since I am at work. I'm sure it's small (since I play pretty small stakes), but still . . .
PokerStars has become aware of two players who were working together in our Sit & Go tournaments to the detriment of other players. You were involved in at least one tournament with these players and as a result you may have been adversely affected.
The players' accounts were closed and their funds frozen pending a thorough investigation, which is now complete. Fortunately the problem was identified quickly and they had only played in a few tournaments before the accounts were closed.
In a case such as this it is our policy to confiscate the colluders' winnings or balances and to distribute them to the players affected by their actions in as fair a way as possible. To confirm your credit, log onto your PokerStars account, go to the 'Cashier' screen and click the 'History' button. Your share will be shown "Credit Purchase", followed by the amount of the credit.
I regret that we will be unable to answer questions as to how your specific credit amount was calculated. Likewise, we are not at liberty to identify the specific games or players in question. Suffice to say that they have been barred from the site and you will not encounter them again.
The integrity of the games at PokerStars is of paramount importance to us and we will not abide cheating or collusion in our games. We work hard to police our games and prevent such instances. In the rare cases where collusion has actually occurred, we make sure that any players affected are compensated appropriately.
Thank you for your continued play here on PokerStars. Please do not hesitate to let us know any time we can be of help.
