I disagree with Hench on this one. Just takes a couple of computerhog monopolists to steer the direction of the entire game. I say this because it has happened several times and because the fun in the game is sucked out for every other player this way. If the dead can't use points, at least weaker players can try to even the field by taking out those aggressive players while they can.
@Infa- An easier alternate to implement is making the wait time for the dead to be 5 posts or an hour before posting again. A possible additional parameters could be how many times the dead can post.
