Fangirls in the Creepypasta fandom are annoying to say the least. I can name several problems, but I'll spare you the time reading that. Fangirls are the type of people that change others' characters for "fan service" or whatever.
For example, some think that Jeff is an emo guy who won't kill them because they "love" him. That's not the case though. According to the Creepypasta Files Wiki (home of the Mary Sues), Jeff is insane and extremely violent. I know that anyone can edit the page, but this is mostly a good description. His goal is to end as much life as possible. Not to have a lovey-dovey relationship with a delusional fangirl.
Same with BEN Drowned. Fangirls : pervert, hot, drug addict. Reality : Kills people for fun. FOR FUN. That's sick if you want to do that. Now, his page looks like it was messed with. It says he's sassy and swears a bit, but he only wants certain people to suffer like him. I highly doubt that. He's a killer, not your toy.
Laughing Jack
Fangirls : sweet, funny, hot
Reality : pure evil, remorseless, violent, enjoys killing and torturing childrenEyeless Jack
Fangirls : quiet, mysterious, hot (this is gonna be a recurring trait)
Reality : dark, analytical, hardly talksSlenderman
Fangirls: you should already know
Reality : cold, heartless, will kill you in an instant, PURE EVILI would include Toby, but I couldn't find a personality. The interpretations are supposed to make them scary, not adorable and hot. Remember that.
