I am fairly new to Chess.com, playing a 2-3 games a day though. In the span of only a few months I have received 2 messages from Chess.com about my opponent cheating and my rating being re-adjusted accordingly. This frequency seems way too high to me especially considering my elo, who is bragging that they need a chess engine to beat 700 rated players?! I understand there will be some cheating as there are always people looking for a slight advantage though I would expect that more at the higher levels. I am wondering what can we do as a chess community and myself as an individual to reduce this?
