I share this computer with my family. My brother and cousin also play toribash. to my recollection I never did anything to get myself banned from the irc so request an unban? Also by who?

What channel(s) are you banned from?

he is banned from every IRC channel

he or someone else in his family did something stupid and got himself pera-banned

yeah...

Nothing we can do about it, I'm sure you have your reasons.
Tell your family to make another account.
Contact the banner.

Closed.

wait remaking another account doesnt work and I dont know who the banner is so...
I'm banned from irc forever? how do i report people?

there is a report button in the bottom left corner

yes you a permanently banned from IRC.

Eiether, way it's your fault you could have taken precautions, as not letting your "family" know the pass, or not letting the computer remember, your pass, or not telling them.
Their, is no proof it was you or your "brother".
