Same thing happened in the event I played in -- maybe this is the same one you're talking about? The U1450 3|2 blitz event from a couple of weeks ago, the "winner" got banned for FPV and the game I played against them in the event was reversed, yet the results went through and are reflected in the USCF results anyway. Chess.com did the ban/reversal 13 days ago, results went to USCF 6 days ago.
Those games were not part of the fair play closure.
ah ok, so does Chess.com basically just reverse all of the games from an account that was closed for FPV even if the other games didn't necessarily (directly) result in the closure?
Yeah sandbagging of ratings has been around since I was a teenager in the 70s. People sinking otb rating on purpose so they could win ten bucks in a Sunday quad LOL. To be fair ten bucks was worth a lot more back then ...
