The first time a category is introduced is naturally the most basic. It will evolve with time, experience, and input from those who are participating and supporting the annual event.
Possibility for the future...a physical location for the Hall of Fame. It would make sense for a brothel owner to be the patron of that since it can be the same as "Brothel Museum"... something you CAN openly and aggressively advertise even if it's right next door to your brothel. When I go to visit the houses again it will be as a client/tourist and that would be a draw. I know I'm not the only one interested in history here.
