Never heard of the Slender Man, but the SCP Foundation is awesome.

Whatcha gonna do, little buckaroo? | i be pimpin' madoka ficsIt's not an urban legend, per se. But it would not fall under "original writing" unless the author of the article came up with a good number of aspects of it to distinguish it from the original - which, given how nebulous Slendy is to begin with, would be even more of a task in this case than with something else.
Crossover fanfiction, on the other hand, is fair game.
