EoEO bans have been around for a long time, and I think the guidelines on those are pretty clear. You're rude in that forum, you can temp-banned from that forum.
I also think having such a specific set of guidelines as to what constitutes a bannable offense only invites people to argue endlessly about whether or not a given situation fell within those guidelines (*cough*). Maybe I am not as hip to this because I've been here so long, but is this actually a problem? Are newer members confused about some of this stuff? Absent any real need for more info, I think the staff has generally done a good job as-is.
And yes, as far as I'm aware, perma-banned members are allowed to petition to have their ban lifted after two years. That timeframe is certainly something that could be debated, though. I tend to agree with Bleys that one year is probably enough, because the staff is under no obligation to ever lift someone's ban anyway.
