It has been happening to me during tournaments that the opponent's lost pieces reappeared on the board later in the game.

And you are wrong.
Oh ok, so there was one beginner standard account closed (around 3 years ago) for "violating fair play". Need I remind you of it?

This is totally false.
Often i found 1300 players that in the first part of the game are a normal 1300...and when them losing, begin to play perfectly and win.
Obiviously when i have doubts at the end of the game i use computer analisys, and often in the second half of the games them did 100% optimal moves......


What?

Ah ok, so i understud well your prev post.
Now i can tell you, your posts are idiot.
A player that kidding on the forum other players with a lower ratings are a totally idiot.
That is what this site dont need; people like you.
Bye.

Whatever the case may be, the forums are an inappropriate place to pursue this. You can use the Cheating Forum (https://www.chess.com/club/cheating-forum) to discuss it or submit a ticket (https://support.chess.com/customer/portal/emails/new) to report it, but you can't talk about it here.
Thanks.
