Is there any good script that could do that? Better if I could have the option to blacklist him(by kick/ban) from all channels or specific channels.

Second question.

..Protect
...Bestow!: { protect $$1 # 3 }
...Remove: { protect -r $$1 # 3 }

I have this protect but are there anything I could do to make the kicker get a kick/ban when the protected nick is kickbanned instead of kick-only?

You can setup a remote script to trigger when the user is banned... the on BAN event fires when a user is banned (dunno about if YOU are banned...) so look up on ban in the helpfile. Once you've figured it out, you can determine how to A) unban the banned user, and B) kickban the banner.
