I have a plugin request to make a plugin to detect wallhacks. Well since this wallhack thing is going crazy all over steam servers. I think its time we get a wallhack detection and kicker. Since Aimbot costs money monthly but wallhack materials are actually free through google and forums. So many many players uses them.
I think with this site for configs/scripts and commands
http://developer.valvesoftware.com/wiki/Pure_Servers
All we need is a Advanced Plugin maker to use that site and scripts and put it into a plugin to detect wallhacks. And I do think it will work well with a plugin.
