In the early 2000s there was a site that showed popular creepypastas like Jeff the Killer and Ben Drowned. One of those stories was known as ''Camerahead''.
This creepypasta supposedly told the story of a 4chan user that stumbles upon a backpack which contained a written note that read "I killed a Camerahead". They are then hunted by the Cameraheads and posts images of them as they hunt him.
In 2010 the site got shut down. Jeff the Killer and Ben Drowned have been saved but Camerahead wasn't. The creepypasta remains lost.
