Looking at a thread SockPuppet made, I'm just gonna leave this up.
The purpose of this is simple. If you feel you need to be banned just post here, and the length of time.
Need to concentrate on your clock day film? Got a big final coming up? Spend too much time on the site? Or do you really just like that duke nukem banned video? You've come to the right place.
If you need to be unbanned, just send a message to staff on IM or email. Usually there's a staff around somewhere on the blast chat who can help.
