The phenomenon has become Tumblr's Newton's Law: For every great fandom, there's an equally vocal anti-fandom, bringing it down a peg or three.

Tumblr has long been the mecca for rabid "Teen Wolf" fans.
After 10,000 entries, MTV selected Riana Elliot's "Side Effects" as the winner of its fanfiction contest.
After over 4 million votes were cast, "Sterek"—the same-sex pairing of Teen Wolf leads Stiles and Derek—came out on top of a poll that fans helped inspire.
Teen Wolf fans are baking cookies for show creator Jeff Davis to persuade him to pair up the show's two male leads, scoring a trending Twitter hashtag along the way. It's so crazy that it just might work.
