Honestly, I don't agree with bid bots.
Trending, Hot page should be for posts with "normal" upvotes from people, not for any post with bid bots help.
I think steemit need to change their UI. The front page need to be change, so people will be able to find posts without bid bots.
Bid bots only make the owner to become richer, this is not decentralized anymore, but centralized on specific people.
When bid bots vote on a post, they don't lose any money and they got curation rewards too from the post they vote, so why we need to pay for this kind of service?
