I see lots of articles here on bidbots: some in support, some against, and some neutral on them. I think that when users sign up for Steemit they take the home page marketing at face value: provide high quality or upvote high quality and get rewards. However, the complexity of the relationship between votes and rewards is not that simple. In fact, it is so complex and depends on so many dynamic factors the its likely that one can only optimize ROI (or even come close) by automating voting: hence bidbots. While there are certainly good arguments for doing this and some bidbots still vote in alignment with content quality, it seems all to easy to design them to maximize ROI regardless of quality.
