My brother has been cheating


Thats a very tough situation. By the way your brother should make his own acount and not just play and cheat on yours.
Stop this topic right now, email support about it or you are going to get banned for publicly admitting everything lol.

Wait a sec, I checked your account and you only have four games which are all losses. And using engine at a rating of 850 means you win everytime. Please respond and explain.
