Tumblerian

Tumblerians are enslaved humans brainwashed by the addictiveness of Tumbler, a hivemind website ruled by Tumbler Support. They always overreact to anything and everything they see, and think they are not human but something entirely different due to side-effects of brainwashing. They are slowly outnumbering the human race, and will soon plan an armada against them in which all of them, even animals, will be captured and brainwashed.
