Is there no rule to the effect that you will be banned permanently if caught using more than one account?
Apparently not. I once informed the staff that my opponent was cheating in a game against me. I was told that she was a known cheater who had once before been banned for cheating. Yet somehow she now had a new account, there was no warning to keep away as this is a cheater, and, in her game against me, if you contorted your eyes just right, in just the right light, then you could miss the obvious cheating. And so no action was taken. She was allowed to win that game. Unbelievable.
Yes I agree, if thats true, then its a lot like the 1953 Zurich tournament!
