Well the problem here is he "Died in his SHAME" which means he's currently in OBLIVION.
Not impossible to come back from seeing as Chris managed to do it, but there's a big difference with that.
Also at best he'd still get "bumped up" to third level of the pit meaning he wouldn't be able to join until someone pulled him out of there THIS contest anyway.
I don't even know who banned him but after looking over his last posts as peach boy, was him whining about him being SHAMED and he seemed to be arguing with Ben and Chris to some extent. (Certainly not a big deal)
The main thing that's keeping him from getting banned again is Thara and Cricket seemed to approve of his posts in that thread. Even Mizal said she didn't mind him but he was being a retard with a shitload of other retards plaguing the site at the time, so got purged with the rest.
Anyway he's free to write whatever he likes obviously. He can even have his old handle if he wants. Just can't join the contest at this time, though I know a couple people were looking for folks to pull out of the bottom level and I can assign him to one of those THEN he'd be able to join a contest. With the 100 point fee of course.
