In a modern advertising system, you have a cost to advertise. The reality is that the delegates should be making more money. One way to do this is to give more to the delegator and not guarentee any payout to the author. Of course no author would use it unless one could draw all the delegators away from current bots. By that Same account, I don't think there is any way to do this due to the coding of how votes are paid out. Maybe its something that can side chained?
