If vote sellers required their customers to decline rewards their impact on the rest of us comes to an end.
The posts still trend, the sellers can set a price that gives a higher roi than they currently get, the price of trending comes down to the curation value of the vote, and the sellers can market themselves as 'new and improved' and 'now sustainably responsible', rather than their current plan 'fu, its our stake'.

But, what do i know?,...im just an old hobo.
