Alright. Look. I don't really know why I posted this. IT's simple, but a friend wanted me to make it for him for his channel. I figured, well since I've never made one before, might as well post it. It's really stupid, it checks a joined user if they are in a channel you don't like, and if they are in it, it kbans the person from your channel.

on *:join:#krimsonsky:{ whois $nick } 
raw 319:*:{ checkwhois $1- | return } 
alias checkwhois { if ($1 != $2) && (*#Killumination* iswm $3-) { .cs kickban #krimsonsky $2 kill user detected. | haltdef } else return }
