You are partially correct. After the sucess of the stories on Creepypasta sites and forums, they were removed and branched off into a subgenre of Creepypasta. However, it still falls under Creepypasta. There is no format or way to write a Creepypasta, and the SCPs were taking advantage of that. It is a subgenre. Slender Man technically began on the Something Awful forums, but has since become associated with several Creepypasta stories. Think of SCP as the inverse: a Creepypasta series that has become so popular that many have mentally disconnected it from its roots.
