My idea is a simple one. Every actor should be marked as one of following three categories: living, dead, and fictional. Furthermore, there should be an option when creating stories that allows the creator to choose which of these three he or she wants to allow other users to suggest. That way, users can shut down people that want to troll their stories with fake actors and actresses, suggest dead actors when they are clearly trying to stay up to date with Hollywood, or some sort of reverse of the previous scenario. I think that this will help prevent a lot of drama before it even starts and it should help users keep their stories more true to their original vision.
