It's that time again, which seems to come round every year or so when this needs to be said. If someone breaks the rules on a thread, calls you a big poopyhead who can't write for butter, or says mean things about your Mom, just report it. Don't try and deal with it yourself. And if you're an uninvolved passerby who sees a developing bout of fisticuffs, just report it and move on, don't try to wade in and break it up. If you're not a moderator the best thing you can do is ignore the two guys rolling on the floor and model good behaviors by carrying on the discussion as if a bar room brawl has not erupted around your ears There have been a number of issues lately where by the time one of the mods arrives we've got a ream of "you stink, no you stink, yeah well you smell worse, well your mom was a hippo, well your's entertains walruses, I'm gonna tell my dad on you etc and ad nauseum. When that happens we're not going to spend time trying to figure out who was mean to who first. Everyone involved in the fight is going to get sanctioned, and anyone standing around like an idiot chorus going 'fight fight fight' may find themselves in the blast radius as well.
