lol, do a search. yes, it happens. no, there isn't much that can be done about it. :)
Cheating?

They are rarely an issue except at higher rating levels (2000+) and possibly in some team matches (probably more likely in league matches), so you dont really have to worry that much about them. If you play enough games you'll eventually get accused that you are cheating. Take it as a compliment, thats what I do :D
Greetings
I am relatively new to chess.com and some concern occured to me.
I wonder if someone would use chess software to assist him/her, If this would be an issue , and If it were , how it could be addressed.
Thank you.
