I'm assuming this is the correct place to post this, but what's the program/method people have used to catch previous hackers. You're able to view your demo and it shows other players through walls and whatnot. Is that a seperate program or a server plugin available for higher admins?

Actually, its hacks, used in the playback of demos. I wouldn't suggest worrying about it too much, you'll get banned for having them on your computer no matter what the excuse is.

So, if I have a demo of a suspected waller, I would just have to use my best judgement with what I can see?

That, then send it to oreX, and then he'll look over it for the final call.

Unless your name is Orex ;)

OOoops, I forgot to turn 'em off.

X-Spectate is legal?

Legal? It can still be detected by VAC as being a hack. The author of that tool is also a well-know hack author. Anything made by him is a no-no in the eyes if vac.

I thought maybe someone had access to something like this http://www.amxmodx.org/forums/viewtopic.php?t=24787 in the servers that most of us didn't know about.

Yes, it's highly VAC detectable to keep dumbasses from usuing it in-game. That's why it's meant strictly for demo reviews.
