Judging by the number of opponents that get accounts closed even where I had no thoughts whatsoever that they had been cheating, I think that it would be near impossible to have an account for years! Almost everyone that gets banned has a newish account... and do you think that genuine chess players have nothing better to do than watch an engine play someone ?!?!
Well someone is 2300, and someone's being bullied by 1500s...
