The problem with this game is that many people have no incentive to post. Why is that? Well, the undead don't want to vote and have their status ruined, per ThePhantom. But, why isn't the town pointing? They have nothing to lose, and if they aren't pointing, they're sent to thread zombie territory.
Perhaps the best course of action now would be to create a list of thread zombies, who haven't posted in days.
