In case you haven't realized, the reward pool is limited. Having someone who easily takes 1-2% of it daily via self-voting is not a good thing. Get a few dozen whales like @haejin, and you will never earn anything unless you have 1 more SP than he does.

Unlike the man in question, @berniesanders actually delegates to projects on the platform. You just can't see it because the SP isn't coming from the account you are replying to.
