I would say Desiree Lee's complete and utter disappearance since Hardiman died kind of puts the final nail in the coffin, morbid pun not intended. I mean she just "Decided to leave the fandom" after that? When "she'd" previously reliably popped up anywhere people were saying she wasn't real to throw a tantrum? Yeah right, you think she'd have the self control not to do it anymore just because her boyfriend died?
But then, Hardiman's fans are still insisting that the cub artist with his exact style who shared his IP address was definitely a different person, so.
