My account was disabled?
Sort:
This morning I attempted to sign Into my account and was confusing told it had been disabled. I had a Friend of mine check my account, and it told him I had been disabled for violating the fair play rules. As far as I am aware, I didn't violate any of the laws of Chess.com.
Has anyone else had this problem? Is it possible to persuade Chess.com to reactivate my old account?
