I want to block this proxy to proxify my site, but i can't block it ... http://www.caw2.com/p2/index.php?vit...ebkl-yvfg.vasb

This page appears as duplicate content for my site Proxy List , and i have a lot of problems with this proxy list being able to rank only for proxy-list.info term.

Tried htacess but will not block his IP or domain, i think he is using a trick or there is something between.
