I agree with everything, but I would like to add something.

If a player requests another player to be slayed or kicked for rule breaking I recommend you warn first then observe the player's behavior. If you didn't see it first hand or the console doesn't have a log of the action then you don't have any reason to do what is requested.

i.e. I joined ZM and Holy was already in there. Someone asked me to slay someone for cade breaking prior to me joining. I'm not going to slay someone for doing something I didn't see. I'm glad I didn't because I made a verbal warning and didn't hear any complaints afterwards.

WARNINGS ARE EFFECTIVE.

As far as camping goes, I'll give one warning to everyone rather than pointing someone out. If I see it again I usually issue a warning "Campers will be slayed for the rest of the map."
