I BELIEVE scorpspammer. I talked several times to him online, and later personally too. Of course that is no proof, and in opposition to some talk here, he was always a strong player, trained like hell, and became better and better. It s more than possible to become top 10 with the way and amount he trained. So nothing suspicious there.
On the other hand, i had several suspicious replays of nine inch that would have made him a maphacker in my book. (no 100% proof there neither). And he is a cheater anyway, bending the rules the way he wants them to be.
In the end, I can't say he is right or wrong. all i can say is that I think relativit is a lot more trustworthy in my book.
