Thank you for your comment @changingworld. You are using bots for the wrong reasons. Using bots is a way to advertise your posts so they are seen by a bigger audience. Your posts consequently get more rewards and people who upvote them, curate them, get more curation rewards than they would have not promoting the post.
What you want is to pay for advertising, get your post advertised and then get your advertising money back and more. I don't know of a place that can do that, certainly not Facebook ads.
