Lol, good topic! When I was an admin over at the now defunct games.velocity.net I used to have a little fun too. There was a no camping policy in place and certain players could never understand this concept. So to help them along a little I would change their mouse 1 bind from fire to kill! They would line someone up, pull the trigger and sit there all wtf!! How did I die? LMAO, Ah, the good old days. Svet
On the BTF Euro1 server, a collossal retard came in spouting crap and interuptting games, basically being an ass because of me (he has this personal thing against me), so at first I bound the following to my +attack key "bind mouse1 +attack; rcon kick Om3ga", then he caught on and changed his name, kept being a dick so I stuffed him the "unbindall" command, hahaha it took him 10 minutes to figure out what had happened xD, some may argue that's admin abuse but bear in mind we're talking about someone who got g-lined from ETG for talking about himself raping children and doing other sick shit. :\
I might note however, that I did warn him several times (as far as I recall) to be quiet and quit disrupting the games, at the time the mute thing you coded was not available, and I did not wish nor know how to ban.
spawn campers will always be cooler than the guy that goes and gets bfg
