I don't mind chasing after the Jester, but they might need some sort of reason beyond that- I think as it is, all the players are like, 'regular people'. Its hard to put like super serious stakes into a game unless it directly effects them and they have a way to directly effect it- as it is, as normal players they can't really do a whole lot to the jester even if they do find him. 

Maybe admins assign them temporary mod powers to ban him if they manage to track him down or something like that.
