I don't necessarily see one about threatening people, there is some stuff about how mods/staff see fit to do things.
4. Flame wars are not allowed. We do tolerate poking fun of one another ingood fun, but hateful posts towards another poster are not allowed.
7.Everyone is here to offer their opinions, so be prepared to have people disagree with your opinions. There is a difference between attacking someone's post (their opinion) and attacking the poster with the latter not allowed. The staff is here to monitor for such occurrences.
I said I thought he was joking, that's why I "moderated" it the way I did. There isn't a rule that everything that falls under this thing gets deleted rule. There is however room for mods to react differently to different things. I monitored it, responded to it other mods were aware of it. I don't feel like I shirked my responsibility, but if you do, I can respect that.
