I know that it can make a post visible, but it is destructive. I can't remember if some of the bots are now burning what they earn, but it sounds like a bad business to me. With the new rules they would be earning more by simply curating.

Sadly there isn't really a good system paying to promoting posts. I think the idea of the promoted system where you burn steem is very good, but the posts should be displayed in the feed of all users where the so called *featured* posts are now.

I am just doing it the purist way and hoping the community will see when I have made a long and work-heavy post - until there will be a promotion solution that will benefit both Steem and the users of the solution, I am not sure it is doable. But I can be wrong of course.
