If you, personally, got muted for downvotes I would have a problem with that action unless the votes became malicious. Unfortunately determination of malicious activity appears as subjective as DV or UV. I'm not sure of a fix for that determination. It doesn't really exist right now outside of a consensus.
DV'ing for what you feel is over-rewards may not be socially acceptable but it is allowed. UV'ing smaller accounts because you feel they're not getting enough is both allowed and applauded. Vote distribution issues appear to be across the board in HIVE, but we're trying to develop something that works for as many people as possible.
