For what it's worth, I don't think a perma ban was necessary with newt. Perhaps he's been a nuisance most of the time, but it's not like he's posted illegal or offensive material. He's done a lot of small (at worst) annoying things. I haven't seen any activity that could be classified as harassment.
I do think drama is a healthy factor in every community and newt is one such person to create drama. I think he should be unbanned in a finite period of time shorter than a 100th of his remaining lifespan.
