Is it possible that the #efu channel can be made so only voiced people can speak in it? There are scripts that can automatically add anyone to the voice when they log in. This way people who say disruptive things or speak of in-game things can be devoiced and rendered mute temporarily or permanently.
That's a pretty easy mIRC script actually.
Unwarranted. If people overstep too much all DMs are channel operators and can handle the missteps.
