As a side note - cheating is really easy. I`m sitting on 5 different IPs every day, if I wanted I could easily cheat. It`s 21st century, internet s everywhere, like go outside, sit in a park, internet cafe, work, friends, lovers...
It`s not like Mr P can check and prove that you are or you`re not a cheater. But if someone suspects you of cheating...well, it didn`t come from nothing...
