They add depth. For example, a simple description of a spooky character isn't as effective as when there's a back story. Take the Creepypasta of Eyeless Jack. His back story of being a former medical student who turned into a demon - like entity after a dark ritual makes him more terrifying. It gives reasons for his actions and appearance.
Creepypasta back stories create a sense of believability. When we hear about how a character like Ticci - Toby became who he is (due to a tragic childhood with an abusive father and a fire that changed him), it makes the horror seem more real. We can empathize a little with the character's origin, which in turn makes the horror more impactful. These back stories also allow for a lot of creativity. Writers can mix different elements like the supernatural, psychological trauma, and mystery to make the horror unique.
