I recently emailed FTP with my concern about collusion I was sure I was on the receiving end of. I saw 4 players on the same 10 tables and each had a nice stacks. I watched for hours and did not play. They seemed to never lose a pot. Well I received an email yesterday form FTP support. I pasted it below.

Dear ponceD,
Upon conclusion of a recent investigation of cash game play, we have determined that opponents of yours were in violation of the Full Tilt Poker Site Terms and End User License Agreement.
In this instance, we have seized the account balances of the offending players and redistributed it to players who were victimized. The calculation was based on the number of hands played against the offending players as well as the amount won or lost against them.
With this redistribution, we have determined that you are entitled to a refund of $10.12, which will be placed in your account in the next 4-6 hours.
For various reasons, we are unable to advise you of the names of the players or any other information regarding this case; we thank you for your understanding in this regard. Full Tilt Poker investigates every concern of suspicious activity at our tables.
