In May of 2014, two 12-year-old girls stabbed a classmate in Wisconsin as a sacrament for the Slender Man, for he apparently came to these girls and threatened to hurt their families if they did not sacrifice their friend. The Slender Man was originally a Photoshop photo put into a contest, but it was the captions underneath that made the stalking, inhumanly tall figure in the background of the photos even more creepy. But the conspiracy theory really falls under the idea that moral panic keeps the public in line. Be careful and don't say I didn't warn you.
