Interesting what you're working on, here. Seems to me like bots would need to be subdivided further-- a manual process. Arcange... sometimes is a phishing warning bot; that's a public service announcement. Cheetah, again serves a service function. Some small bots like cuddlekitten only interact with people who have upvoted/followed them... making them "requested" and probably harmless. Some might be classified as "nuisance," but harmless (steemitboard?). Some are bot-spam.
I would have to say some of this would be very hard to fully automate. But still following this with interest.
