Was Tony the Tiger Driven Off Twitter by Unbelievably Horny Furries?

Its obviously a 'self aware' chan joke. There is a pretty big chan culture and furry culture overlap because of the many conflicts between the userbases. Eventually the furries won and now inhabit quarantine boards on 4chan.

The whole "brony" thing, for instance, was started on 4chan and started a practical civil war that ended with the dedicated quarantine board /mlp/. Furry and mlp porn was so frequently used to nuke threads on various boards that another quarantine board, /trash/, was created to hold everything that no one else wanted to look at. The idea was that the spammers would be happier hanging out, umm, discussing their artwork of choice, and forget to mess with everyone else. It seems to have worked actually.

As for over the top, well, we are talking about people who spend thousands of dollars on animal costumes
