I disagree with bernie's self-voting and really self voting in general. I also disagree with his using his power to downvote people he doesn't agree with. Now that we got that out of the way.
Rancho can do what he wants, but the community has a bit of a responsibility to correct his efforts if they don't believe in the worth of those posts. Otherwise, one whale could simply by the whole pot and kill steemit. I don't believe that haejin should be downvoted to 0, but honestly, he's doing pretty well.
