Enable scriptenforcer on your server.

No, i allow use custom scripts for my users.
I have build server and some clients have his own client scripts, no other way to fix this shit?

Either use the ncp plugin, or CreateConVar (SERVER, not client. I hate it when people break my commands.)

What is ncp plugin? Link to this plugin please.
