I doubt the USCF is automatically notified of any cheating on Chess.com. Hopefully the TD for that tournament will report the fact to the USCF and then the player should be sanctioned and your game re-rated. (At least that's what seems proper to me)
It is also my hope, that even if the player creates a new chess.com account, he is not allowed to rejoin the USCF Members only club... which would prevent him from playing in an future USCF Rated tournaments. (at least through this club's events)
Hopefully, one of the admins, or the TD will respond to your post.
In round four of the October 1 tournament, I lost. My opponent played very well, 92% accuracy, but I didn't think much of it. A week or so later chess.com informed me of a fairplay violation on October 1 and a refund of my chess.com rapid rating points.
Sure enough, I saw on chess.com that my opponent in round 4 on that day was banned for fairplay violations.
The official USCF ratings for the tournament came to my inbox yesterday. I looked at the detailed records and found I was still given a loss for round 4, which of course cost me official USCF online blitz rating points.
The player in question is STILL banned from chess.com, so that rules out the possibility that an investigation later cleared him or her of the fairplay violation.
My question is: if a player has a fairplay violation in a USCF online rated tournament, shouldn't the game not count toward my official USCF ratings?
