I pretty much think the same as you regarding bidbots. I used to buy votes for others before #newsteem, but I've stopped doing that, because I don't want them to become a target of the "all bidbots are bad" crowd.

Like you said, there are still cases where you could say there is bidbot abuse, but you have to look at the content of the post and find out what it's all about in order to decide whether it deserves the rewards or if it's overvalued.
