Well, I know that there are special web sites 'bout “anty-cheating” but I had just returned from one of those (they didn’t know the answer for my question) so this is the last place when I can find help: the forum of ET’s creators…
I have server with cheat cvars and md5 checks so most of (or all) cheats and hacks that can be found at net should be sniffed by my anty-cheat sys…
I also use pb’s auto ss.
This is a one of many ss of some guy…

This look like ss block but at pbbans, admins aren’t so sure bout that. They dont know what to do with this fellow. Can somebody of You all help me? Maybe this guy really dont use a hack (?) Maybe is it sth bout his cfg or graphic card for example?..
(hope that my english dont “prevent” you from understand my post ^^)
