Is it a vendetta against CrazyStone or could it be some kind of pump and dump scheme? What I mean is the scheme where you basically give a bunch of your rating points to another player for safe keeping, recover them by playing normally against other players, and then take them back from the original player. It's even possible that he operating the computer player he was using which would make this easy to do. The admin can probably check to see if the login times frequently coincide or if this bot plays a lot of other players or mostly just him. And maybe it's just a coincidence?
