I say yes, he should definitely be unbanned. He was banned pretty lightly to begin with. His main problem was falling out of favor with certain members whom he kept lashing out at due to being treated in a way characteristic of those members. The blame is partly on Koobie himself, of course, for reacting to hostility with hostility. There were also genuine attempts to criticize his writing in a civil and constructive manner, but that never went over too well. That said, this forum has had people who were far worse toward other members and who were never banned permanently.
DISCLAIMER: the above is based on my memory of some of the discussions that were had and is subject to failures and/or inaccuracies in retention as well as my possible failure to have read some of the things that may have been and may be considered particularly incriminating in Koobie's case. I hereby concede that alternative interpretations of Koobie's interaction with other members, and the reasons behind his permanent ban, may or may not be more accurate than my description above.

Looks like we're not going down after all, so nevermind.
