What is the most vile and rude forum?
I have heard and seen that MadonnaNation and BreatheHeavy are one of the forums with rudest people. I remember we were talking about it, and MadonnaNation banned someone because of Gaga avi

and you can't talk good about her either.
GagaDaily is one of the nicest ones, users have avis with Madonna/Katy, there are many good discussions about them, Katy was voted as the most liked artist (except Gaga), there are many people stanning for Rebel Heart
Not music forum, but men's tennis forum is super vile, there are users dragging others, hating on players, always accusing of doping/cheating. And the mods do not punish evil users at all
