The problem is also that the impact of zeroing a post removes that post from trending lists (as Kenny explains in his post) and is essentially giving the power of editorializing content to those with the largest stake.
Like it or not, these posts are a scoreboard and the upvote reward total is how the system decides which posts are worthy of more eyeballs. Allowing several accounts to choose who is on the trending lists is the furthest thing from decentralization.
I suppose I stopped looking at the score board when I stopped using facefuck.
So I seem to be a bit more immune to the illusion of the numbers game.
