It depends on whether you are guilty or not. If you are, there's nothing we can do. But if you aren't, which most of us should believe, then you can report the users accordingly using the Report feature.
In many circumstances in the past (while I was still active playing on this site), a small minority of my opponents did something similar, and I reported them (I didn't need to send any proof even though I saved them post-game). While not every user gets warned, I was still notified by Chess.com about "actions" taken against a number of them. It's more likely their account (rather than yours) will get restricted.
People keep telling me I am cheating when they keep blundering a winning position. Are they nuts? I never cheat in chess in my whole [removed -- MS] life. I just watch tal games and keep doing nonsense sacrifice (not accurate just to intimidate ) and then they go to your profile and tell you cheaters or message you that you are sore loser. SMH.
