I don’t use bots. I have in the past just to learn how it works. Yes many of the top posts are sending Steem it SBD to bots, the bot upvotes their post with enough SP vote % that it should return their initial investment, plus profit, specially if the visibility garners more votes from the community. There is a chance if the price of Steem plummets in the 6 days until post payout you could lose money on that action. It’s just stupid. Hopefully one day it will go away. There are posts that do get legit votes for that amount but unlikely.
