Good idea. The way I see it, its like there are two sets of rules. The first set is "what isn't allowed" and the second set is "what should be done when someone breaks a rule."
I think the first set is pretty good. I'd include two things, which as far as I know, haven't been included: spam users will be banned & any spam topics deleted; trolling will not be allowed.
I think the second set of rules could be loosened up. I have absolutely no problem with the mods having leeway to lock topics that, in their judgement, have turned into flame wars. I have no problem with the mods using their judgement to determine if a user is
trolling, or to warn a user that despite what their intentions might have been, the effect is the same as if they had been deliberately trolling.
So basically I think the rules have been fine, but the enforcement should be tweaked so that mods can deal with that one user in a thousand who is a source of a lot of problems, appears to be doing it deliberately, and contributes little or nothing. That is necessarily difficult to precisely define, I understand some users might not like anything that isn't precisely defined, but I think we can live with it.
