Stakeholders win. Authors lose.
When you purchase a banner ad there is no issue with your stake appreciation aka curation reward (that has been intentionally pushed towards equalisation by the hardfork) is boosted by misplacing some author rewards to your own post.
It only takes a minor downvote to discourage people from voting questionable posts (for the fear of ineffective curation returns, that is).
FTR, my position is that effort should not be a factor in rewards. Lack of content an autoposts is the dangerous mixture to me.
What is specifically "dangerous" about a "no content" "autopost" ?
