Also great post, brings about great discussion points. so thanks.
I agree with Hive account@anyx on #rule 1 tho. A bot can (and maybe even should aspire to) provide value in other ways. Now also interesting to discuss is what we mean by 'value' maybe?

As for the last rule of subjectivity, it is interesting, cos especially some bots, as in the case of cheetah, are essentially an extension of their human's moral-values/drives/motivations.. the more the bots have a unique 'persona' the less generalized comments would get I think. people would make more targeted remarks, I'd suspect. I also agree with upvote/downvote being reserved for human interaction. Unless someone by some machine learning magic one day comes up with a smart-ass bot who actually has a taste and curiosity of it's own. =D
