Changing to 50/50 would just get the vote buying to change how they charge for what % to 'ROI' give, while the delegators and owners would make even more than they do now. That's the outcome I see. Vote buying would continue,a s long as they adjusted and still provided a positive return for the amount of money sent out.

If people want to buy votes, it's not about eyeballs. It's about making more money. Thats why the bots calculate their votes based on money sent to give an ROI that's positive, not negative. Would people use ocdb if the return was negative? Would they use any of the many other bots? Maybe a  few would, but that would be the people who are willing to actually spend money to get more eyeballs by reaching a high enough payout to get the eyeballs (like $100). Buying votes to get your post at $10, $20, or even $50 isn't getting anyone any more eyeballs. You have to spend a lot more. That's when it has an effect on the trending page. The majority who buy votes are doing it to get an ROI in a rigged voting scheme-platform where you can just pay to get more rewards. THAT is what makes Steem a sad joke imo.

And you curate, or anyone else, because you care to reward content you value, which is how the whole system is supposed to work (and in exchange you get rewards too, curation rewards). That's when the platform gains more value, when the content is rewarded because its valued by curators. Again, vote sellers just want to make easy money by doing 0-actions, if they cared about rewarding content they would be doing that. And vote buyers want more money because curators aren't curating them, they have to buy votes to get rewards, not earn them.
