Once upon a time, in the magical land of Hogwarts, Harry and friends were attending a course on writing fanfiction.
"Now, listen carefully," warned professor Ssonic. "If you post an authors note as a whole chapter, your account could get suspended. And we'd hate for that to happen."
But Ron was too busy snogging Hermione, and Harry was staring off into space, thinking about his dead godfather to listen to the smart professor. Then, when they posted their stories on FF.net, they made an author's note demanding reviews. Unfortunately, someone reported them, and their accounts were suspended, never to write again.
Harry sunk into a deep depression. Voldemort attacked Hogwarts and killed everyone. All because none of you read the rules and made stupid author notes.
