This has been previously suggested and I don't know how likely it is to ever happen.
However, discussion of cheating, potential cheating, cheat prevention or detection are not allowed in the general forums. If you want to discuss join the following club https://www.chess.com/club/cheating-forum
Everything about chess.com is great except the tournaments. Allowing obvious cheater accounts especially brand new accounts that exhibit all the red flags of cheating just tells me chess.com doesn't take it seriously. From time usage, 95+ accuracy as 1700 or 2000+ elo in rapid but 900 in blitz, puzzles rating 1100, new accounts with huge win streaks, moves that are clearly out of place for their elo in conjunction with the time usage, 3-5 seconds for obvious opening theory moves where even 1200 elo players would play instantly etc.
The tournaments are free and offer no prize sure but that's not the point.. The tournaments are meant to be fun though competition is fun isn't it? Every tournament I've played if you play the entire tournament you're nearly guaranteed to play at least one cheater. Why should this be the expectation for us? Why is it so difficult to attempt to implement at least some simple measures to limit the nuisance?
