I actually think Hive account@yallapapi is one of the better trending users, and he's super up front about his bot use- I don't consider him to be a problem, and if more of the bid-bot users were like him, well, the front page would be much nicer.

But yeah, Hive account@transparencybot comments should be at or near the top of any bid-bot promoted post, even if it's a high quality post.
