So I lost about 100 rating points to a clear cheater that is like 115-3 and is almost 2000 rated now, yet he's terrible in rapid with a record of like 26-11, with a rating of like 600. Clearly this guy is a cheater, so my question is if I don't play another game, do I get all my rating points back?
It depends, but if an account is closed for fair play violations, there are rating refunds in the pools they were closed for, but there are some limits.
