This is a simple blacklist script for bots or yourself.

!blacklist ;; adds a channel to the blacklist
!deblacklist ;; removes a channel of the blacklist
!blist ;; returns the blacklisted channels and if the channel your on or the requested channel is blacklisted at the moment.

Its obvious that the channel isnt blacklisted if you can trigger the command on the channel itself. I included it anyways.

Change #staffchan in your own channel.

goes fast by: CTRL + F then put searchterm #staffchan and replace with #ownchannel

Post bellow for fixes and feedback.
