hello, how to block serverinfo cvar? some players using this cvar for activate net_graph , developer and etc cvars.

[fysiks]

"serverinfo" does not appear to be a cvar. Also, it contains information regarding a server, not a a client so I'm not sure how you think it's related to client-side settings like net_graph and developer (neither of which a server operator needs to care about).

[Depresie]

you may block players to use certain commands while they are on the server, with hooking the command and returning PLUGIN_HANDLED, but if they already have them turned on, i dont think you can do anything

in other words, you should better forget about it, also, you are not supposed to mess with people's client settings

He's probably trying to disable some settings that will help the user to gStrafe ( scripted ).
