ATrader is a cheater

This guy has numerous tgp sites listed below. IMO he is 100% cheater.
How I catch him. I redesign a site yesterday. I move my links from front page to archive pages. He was my no. 1 referrer, but after the change his productivity went from 120% to 0%, whereis my other trades productivity increased over 200%
Then I look at 2 other trades I have with him and see.
big-fat-bitches.com 86.72% proxy hits
older-hardcore.com 96.64% proxy hits
