User blog comment:Speccyemerald/How excatly do the mods and rollbacks know that is a trollpasta and what isn't? Why have the rules on pastas been tightened?/@comment-10789912-20151128191543

If it is purposefully bad, it's a Trollpasta. If it is made to scare, it's a Creepypasta. If it's a really bad Creepypasta, sometimes it is uploaded to Trollpasta under the "Pastas trying to be good when it sucks enough to be a troll" category.
