When does a thread become inappropriate?
I recently participated in a thread entitled "I hate cars" or something, which quickly devolved into a flame fest, and very soon thereafter, it was closed. I don't dispute the mod's decision to close the thread, because it was actually getting pretty juvenile (mea culpa), but I do have a couple of questions, purely for future reference:
1. At what point does a thread cross the line into "inappropriate" territory?
2. Who decides whether or not a thread has become too icky to deal with?
The reason I ask is because I sense a bit of inconsistency, and I'm a bit confused. The "I hate cars" thread was definitely flame-filled and served no useful purpose, but its general tone was rather playful and mostly harmless. In other areas, such as the Advocay and Safety forum, I've seen much worse threads, very nasty, even destructive ongoing arguments, full of rude personal insults, go on for days or even weeks at a time. Does the moderator only intervene if a user makes a complaint?
I guess what I'm looking for is a list of guidelines for using this forum. I'm here to get information and to amuse myself, not to offend people...
