If we were really biased, Buzzard, there would probably be a half dozen or so folks banned who currently aren't. We try to treat everyone fairly. Ultimately, our goal is to make sure that these boards are a fun place to hang out; if someone is ruining that for other people, they'll be treated in a manner which we think is appropriate.
I'd much rather be on a board that takes personalities and histories and intent into account, instead of a laundry list of rules, so we run the boards that way. Does it work? Well, I really like it this way, and it makes Morrus happy, so we'll keep handling things the way we have been. If you can give me actual examples of bias, I welcome you to drop me an email.
