Dear @truthforce
If you change it to 50% there will be more people who buy Steem just to use their upvoting power to make 50% on upvoting anything
I hate to say that, but I see it exactly the same way. Those who self-upvote will not stop. They will receive less as an authors but more as curators. So it won't stop them.
At the same time bidbots will be growing twice as fast as they are growing now (after all their curation rewards will double).
Yours
Piotr
