Here in Brazil, there are many players who can only play using the config scripts.
I'm trying to extinguish it in the servers which I am administrator and want to know if there is any way to put a command in the cfg that completely restricts the use of these scripts.
something like -ruleset smackdown that is earned in the EQL.

someone who can help?

Yes, by setting proper FPD value. Check out http://wiki.quakeworld.nu/FPD (bits 14 + 15)

right, but the problem is that they use the rotate command and do not know WHAT the pitchspeed and yaw would influence these codes.

If it solves the problem, then what's the issue? Or do you mean that the rotate command is still possible to use? (which i don't think it is?)
