so i went back and checked all of the funky users and it looks like they put a secret message in the input boxes.. but if any part of the message was in the password field it'll be pretty hard to decipher because I only store a hashed value of the password (the original text is not recoverable in any reasonable amount of time).
anyway for your viewing pleasure a little snippet from the database (emphasis added):
