I was wondering if those video_check_glclear and video_check_lockpvs are still working...? the user is able to enter the game with this option as 1 and change it during gameplay. Think this is some that was beeing used in ncservers and whenever the client tries to change this value, gets kicked. This is still usefull against some hacks. Addcvarban and addcommandban do work but, as you know, only during connect and gameplay by the checkcvarbans.
Btw, is there a way to schedule checkcvarbans to run from time to time? p.e. every minute...
Keep up the good work!
