Maybe the other is unaware..... you know; a Jeckel and Hyde thing. That way neither would be breaking any rules. Hummm ;-)
Is Erik really cheater1?

Well the funny side to this is...Erik knows the ISP of the Cheater, knows his location based on the ISP and IP address and even if cheater used fictitious email addresses the moment he's logged -on , he is seen. Wifi? well, they have their ISPs too. The moment a player registers, his location is identified. Im no FBI, CIA or spy. But I used to be a Network Engineer, i know where pranksters,hackers are when they try to access our system illegally. But if cheater did not do anything the brake the rules,erik cant ban him on principle. So Erik knows the cheater technically.
Lots of assumptions there. I'm sure you've heard of Anonymous Proxy Servers. You cannot rely on the IP.

Actually proxy servers still contains rights,permissions and restrictions in binary codes very readable to a program administrator and yes they can still be traced.The same way a hacker in the 90's was traced even with his anonymous proxy server approach and pc hopping style (READERS DIGEST). It's just good that the "cheater" is toy-ing around here and not in some government sites. Because no matter where we are, we use lines (copper to fiberoptics to satellite). Military invented this technology and they can work around it.So i believe ERik technically know the Cheater, But if the CHeater did not violate laws here, then he's a free member to play.

Don't knock on the guy who started this post. You have to admit, there is so much hatred and controversy between the two parties, it does make you wonder if there's something going on or not? I mean, if some idiot I didn't like was in my house, I'd just get up and kick them the %&$#@ out. So why doesn't Erik do the same?
I don't believe, by any means, that cheater_1 and erik are the same person. However, I believe that cheater_1 draws enough attention, and amuses enough people in the forums, that erik allows him to stay. He helps chess.com to be successful. As well as this, cheater_1 has not insulted anyone personally, and has not cheated without blatently stating it to the opponent. He has not made a breach in the laws of chess.com.
I am cheater_1! Err, no, wait a minute, I am Spartacus! ... At least I think that's who I am, maybe I'm somebody else. Actually, I'm not feeling like myself today so I could be an impostor. But, really, who cares?
