I don't know why people even entertain this shit.
When they don't get the attention they want, they either change their behavior, or go away. Either option is fine with me... That pretty much goes for the ones who are constantly doing battle with them, too.
Just 20-30+ pages of bullshit over and over again....
It sucks, because that's usually the point where the good posters start falling off... and all that's left are the ones that no one even wants to hear.
