tl;dr because this is very long: A famous fanfiction author turns out to be a real creep. He uses a lot of pseudonyms and sockpuppets, convinces some of his fans to move in with him, claims to mind-meld with fictional characters, insists his fanfiction is better than Harry Potter itself, and has questionable views on women. Oh, and he was involved in a triple homicide and used the girl’s death for fun and profit!
