I understand where you coming from, and indeed, it are not the buyers who profit a lot, it are the users who rent their SP to bots, or use their own SP for their own bot who profit a LOT. Before we could rent out SP to vote bots, we could use SP to give a vote to some post, own or some other users post. Now, a bot vote giving 2$ on a post may get 1SBD for that vote, which is a lot more than any users could get when manual or auto voting posts and comments.

You also seem to move all issues to Steemcleaners. Well, that is a very simple way out, dump all issues onto them. I can tell you, Steemcleaners is by far not taking care of all the abuse. For what reasons, I don't know.

How cool would it be all the SP in the hands (own or rented) by bot owners to be combined and given to curation teams! Curation teams are more and more required to give votes to better content, whatever 'better' means. In reality, curation teams are loosing their SP, from users who gave/rented some of their SP to curation teams in favour of renting it out to vote bots.

Your calculation on post/comment rewards is wrong btw, the profit is even less, when SBD has a higher value than 1 US$. That said, the profit to the bot owner on a SBD based bit is larger.

What a particular hate (to use a very strong word) is when people try to bring a story! I don't know you, and I have nothing against you personally, but you brought a story. Why am I saying that? Well, because you brought half the truth, and not the complete truth! Of course, that is allowed. Nobody has to be objective when bringing their opinion and knowledge, but it is misleading and it reduces your own credibility when creating posts like this, at least in the eyes of those who understand the topic from left to right.
