I wonder if most of the most obnoxious abusers aren't on dial-up? In that case, the IP changes with every log in. I also wonder if the Admins don't already keep track of the IP of those who are banned. It seems to obvious to me that they are and would be. If, however, someone cares to go to the trouble of changing an IP just to come back in to RHP with a new profile, only to cheat again, for absolutely no "material value" whatsoever, then I don't think anything will every stop them, but they are beyond absurd. Further, I don't really care that much. Let them. I'll play an engine and enjoy it and consider it an exercise in chess. A constant engine isn't a problem that I can see. I am only bothered by the occasional "stealth" engine user who pulls out their "computer friend" to win a clan match, a tournament, or a league competition. I don't see them ever being stopped. Not in RHP, not OTB, not in real life. I just play to enjoy the game. Their punishment is in knowing that they didn't win anything. Their little computer did. It's the equivalent of riding a bicycle alongside a Marathon race and claiming in your own mind that you won. Whooweee!
