I downvoted this because as with most if not all complaints about downvotes, I think it was WAY overrewarded (in large part, as often the case here, by autovotes or oblivious votes).
That being said, I do agree with one point, which deserves more exposure and discussion:
Remove HIVE rewards altogether. This is my favorite option, but with some non-negotiable caveats [read caveats above]
With individual communities in charge of rewards they can create their own rules and practices for voting.
