The thing is that you don't force them. You are voicing your opinion. Curation is both way. If this was a star system like amazon people would see almost anything less than 5 full stars as negative. I don't agree that you are Stealing because you don't have their rewards, and they are still being voted on. Essentially a vote for the other team is a negative for the home team because voting is a zero sum game, curating for stars would yield similar problems but we have to recognize what stealing is and what curation can look like.
