indeed the ban was upgraded a perma on feb 19th (as seen in this link i posted).
What im guessing is that he probably designed a bot that goes through community sourcebans and search for keywords such as "speedhacks" or "wtvr hacks or scripts" and pull the steam id of that demo, and perma ban on his site...
It's a fucking retarded possibility, but makes more sense than anything i can think of -.-
