The WWF Facebook Fake-Out occurs after a user clicks the “Like“ button on the WWF Facebook page. When the user navigates away, they will find a desolate world of Facebook. Searches for friends will come up empty. The News Feed will be completely blank, until one status update appears from the WWF, "If we don’t take care of the planet, humans will go extinct". Facebook then returns back to normal and the viewer is asked to invite friends to also “Like“ WWF.
