So my philosophy is to have broad, general mission statement type ideas and then let the specifics fall into place under those.
What I like about this list, though intended to be humorous, is that it gets at the intention and motivation of posters and I feel that is much more important.
It has always been a huge pet peeve of mine to discipline people based on 1 interaction or post. First of all, even the best of us get drunk and post vitrol at 4 am. Second, I think it is much more damaging to post ongoing crap that technically falls within the "rules".
When the rules are specific it also means people argue minor, meaningless points and that drives me crazy. In my 7 years experience as a professional forum moderator, I heard SO many times shit like "Well, I didn't say "YOU are an asshole, I said "People who say what you said are an asshole, so technically I wasn't flaming HIM."
Calling someone an asshole isn't the part that should be against the rules. It's how they use it. I could tell someone to eat shit and die and based on my motivation, it may be ok. But I could also just say "whatever" and be completely disruptive.
I don't anticipate banning folks, and I will always give warnings first (unless it's an obvious troll or spam account), but I just want everyone to know upfront that there are no specifics and I'm looking at overall and motivation, not specifics.
I want healthy, intelligent debates. That means folks may be a bit rough and call names. I'm ok with that. If it crosses a line and someone actually takes offense, that's why I've set up the Duel of Wits. Get it out and get over it.
In general I don't want arguments or pettiness dragging down a real conversation and will moderate based on that.
