What will happen is that only dishonest or greedy person will end up using the bid bot. if there is only one person using it they will probably bid only the lowest bid possible...
Right now I see no solution to this. Dan Larimer was against vote selling and I think under how Steem was originally design vole selling would have been a lot less prevalent.
Vast majority of steem users are great, but the steem that exists today is not what I created with its linear reward curve. I did try to fix it, but the community was very much against it and so was Steemit inc which no longer wished to follow my advice. I always try to fix past creations before moving on. @dan
I wrote him a little letter on that post.
I guess a solution is hidden between the lines on that post as well.
In this post I suggest posts be moved to promoted and away from trending the moment a bid bot is detected. Combine that with negating votes and rewards once a bid bot is detected(there's no reason to pay an advertiser for advertising to us, that's not how the business works) so people can still see the post, take interest in the author, find their blog and vote for content there rather being able to vote for the advertisement/promotion. The more the member wants to put in, the higher the paid slot in promoted. The ROI should come to the author in the form of leads to their blog much like true promotions/advertising. If people do it properly, it works, and can't be abused for a simple ROI for no other purpose than abuse and leeching profit for nothing out of the reward pool.
The solution is to simply act on it.
Everything here, combined with a few other things I said only paves the road to true advertising that involves bloggers placing their own ad banners on their regulars post. Clicks could generate ad revenue to both blog and advertiser. Everyone still makes money. No abuse. I'd say more but at this point I don't have time to get into details.
