How are they a racist? I'm guessing they said something to you earlier in the chat? If that's the case, just report them. I rarely look at chat during games because lots of times it's rage bait - and that's not connected to any one country.
Also... just going to point it out, but saying every time you see an American you're going to quit. That itself is prejudice and racist.
Also also going to point out that this forum post will probably be locked. You can't name players and make accusations in the forums.
i just get this racist yankee settler that plays one move then pretends to have a phone call, insult me when i explain that i report him for cheating
he goes on chess.com just for that why you don't ban him forever including his IP ?
