It's good that you reported him. Chess.com does take action. If you look at the monthly reports, you can see how many accounts are muted and closed for abusive actions. Last month, it was more than 100,000.

This site is so toxic, some beat me and started cursing and insulting me for no reason at all, calling me a loser and other stuffs,i offered him a rematch and he accepted,after the match starts he aborted the game and then started to calling me a sucker, what's wrong with these people?
I reported him, but chess.com won't do anything about it, people like that should be banned from this site,and that's not the first time this happens
