nearly done...

but WTF? i cant get on irc... some security thing and it says im banned for a month

That happened to me as well, very annoying.
Remove your IP from http://cbl.abuseat.org/lookup.cgi
see if that helps.

yesterday it worked by just changing my nick(or maybe that didnt have anything to do with it? doent matter. im happy it worked).

but thanks for the link. ill try when it happens again.

No it doesn't, so called g-lines (thats what happened to you) are host specific and not bound to the nickname
