Personally I could. Not because it made more in rewards than me but because I disagree with it's rewards in general. That's what downvotes are supposed to be for though.

All that being said I seldom use downvotes due to most of the content I disagree with being part of a protected class that gathers more than any of your posts I've seen. My downvote is merely symbolic and would only lead to retaliatory actions so what's the point?
