Potter Fanart Wank
This one's fairly simple, but amusing nonetheless.

Over on LJ, there is a journal called potter_bunnies dedicated to fanart pictures of Harry Potter characters as bunnies. It's decent art, and fairly cute, but the creator, jlarinda has specific rules she wants followed, like no spoilers being posted and, for some reason, she won't affiliate herself with any art journal that posts Remus/Tonks.

Sometime recently, another fanart journal called geo_potter affiliates itself with her, and then posts a Remus/Tonks picture. jlarinda asks them to remove the affiliation. They say no and, supposedly, mock her in their journal.

Jlarinda flips out in potter_bunnies.

She insults the other journal completely, and encourages her minions to go over and flame them because she thinks it's fun.

Some people stand with her. Some people stand against her. Some people try to stand with her while insulting other communities she's affiliated with.

The best part is, in the end geo_potter deletes itself.
