disagree with it or how much you are receiving in rewards...

I will agree with you that opinion downvoting is a dick move. But... You do realize the reward pool is both a fixed and shared resource? That means the more people who "move along" when they see abject over-rewarded posts, or posts designed to milk the system, the less rewards there are for the people actually working hard who deserve them. One reason the rewards have improved for you, for me, and many of your readers is there's folks out there willing to not look the other way when it comes to exploiting the reward pool.
