What can cause a story to be retroactively expunged from a FurPlanet anthology?

One author’s work caused a firestorm of controversy, pious wailing, and gnashing of teeth. But how dangerous can a piece of fiction really be?

Personally I love danger, controversy, moral abominations, and terror in fiction. I can’t think of a better place for those things.
