User blog comment:MrDupin/Why Jeff the Killer isn't a classic/@comment-2240864-20150922140000

Jeff is a classic because it gave teens and tweens a something to fall in love with ...for some reason. It's that hormonal storm that makes them weird creatures.

The reason Jeff spinoffs don't define this genre is because they are all the same story, just with different characters. Everyone who posts a JtK knockoff wants to replace Jeff's character with their own, or introduce him into their lives through their fiction.

They don't define the creepypasta genre, but they are a direct product of Jeff, and for these people it does define what internet horror is. It has to; why else would they keep writing about him or trying to imitate the story?
