Cheats for L4D do exist but are very few and far between (unlike BF2 which was riddled with them)

There's 1 particular 'popular' one that I've downloaded form the piratebay (complete with trojan ) and added to hacked (non-online copy of L4D) - after a little analysis I've developed an anti-cheat detector for this hack. Since it's not approved by VAC I've uploaded this anti-cheat tool it to the server as a mod.

For obvious reasons I can't actually test this online...

It's on and running on both servers now, so please post here in the unlikely event of getting kicked or banned for a false positive

[Edit: some people online today, no problems so far]

awesome hopefully custom anti-cheat scripts will be welcomed by valve instead of pissed on like ea did...

yeah, valve actually do stuff

I submitted some previous code to them and wasn't ignored like good old EA

yaaaay!!!!
