Most of the flame wars I noticed where about RaptureVision and SheFights. In particular there was a guy Kinght of Halos who was kind of toxic. The moment he saw SheFights he would take over, to any sentence he would respond with a page, and kept on and on.

He would have been an ideal candidate for deletion, except that he was right. He had been injured by SheFights girls (sorry in my book they were not even close to mistresses) so he had a valid grudge, but the way he was going about it he was alienating everybody.

Or you have Roy who obviously wrote fabricated stories but they were no harm, and created interesting discussions.

Both cases show the difficulty of going after content.
