grenv: Perhaps we need to set up a team of "agents" to root out the cheats. :)
One of the players is someone who I pointed out to Fencer a long while ago. Filip took action against him but he's back to his games and now seems to be part of a team or interacting with them. Paully has done some cheat busting but has stopped playing and thus stopped detecting.
I think the most effective way to hinder these people is not to allow new accounts to go to 2600 on the first win. If players start at some lower value and work their way upwards through good play then there's no way for new accounts to be so easily misused.
