Thanks, yes I mentioned the obvious self-interest of bidbot owners and their delegators. From a personal usage point of view, just be careful whether the "curation toggle" on the bot-tracker is ON or OFF - the default is ON, which deducts the 25% curation rewards. If you have judiciously upvoted your post before the bidbot, you can make back some of that curation rewards.
I cannot peer into people's brains but some of the bidding I've seen could be naive (to be charitable) but others seem quite malicious in knowingly ruining the ROI, including, of course, their own, hence the deduction that such "rational actors" have other intentions. We shall see!
I found the info on bot tracker to be inconsistent at times
