There is none. Be as rude and insulting as possible when ever there's a chance. Misspell a word and you get a page and half of ridicule. I once typed "Sean Peyton" by mistake which resulted in multiple pages of insults and ridicule. For a simple mistake. The kind of behavior that would cause a fist fight if you treated a physically fit man on the street like that.
What's up with that? One poor guy made his first post ever and it was weak, but not to the point that it deserved the abuse that followed. And that's just one example I've seen over the last few weeks and it's getting worse.
Lighten up people. Rude is rude no matter where you are.
