Non-existence confirmed

Basically, this is stuff that was eventually confirmed fake after a long search for them, to the disappointment of the searchers. They were either the product of the Mandela effect, a hoax of varying effort, or a Creepypasta that was so plausible, searchers thought it was real.

Note: a page should only go here if it was strongly rumored before being confirmed fake and/or had a big enough search for it.
