It's why everybody with money here has stopped selling their vote, and now "gives it away".... but only to posts that are guaranteed to make at least $10. The more a post is worth, the more the upvoter gets for upvoting it. It's basically the opposite of how curation is intended to work, since now, everybody all just gang-votes the same post, to maximize their curation rewards. (Creation rewards are now so small, that very few people are bothering to create content anymore. Unless they're on the list of people guaranteed to get at least $10.... then upvotes are extremely easy to come by.)
Long story short, if you don't care about the blockchain and just want to maximize your share of the rewards, only upvote already-successful posts.
