(I have no information about the specific topic of alleged CTH bots/“bots”. I’m not asserting that any particular group is using bots. I’m just speaking generally about the topic of what counts as “bots” and what doesn’t.)
I kind of feel that in a case where there are many accounts using identical text (which is too long to be identical by coincidence) (e.g. in replies to something), it is probably fair to call these bots, even though one can’t rule out the possibility that the automation is as small as just copying and pasting the same text into different accounts + something to open windows as different accounts viewing the same tweet.
Like, maybe that setup wouldn’t strictly count as bots, but really only because it hasn’t been automated as much as it could be while having the same result.
So, I think it is probably fair to call that observable-phenomenon “bots” even though it might not always strictly be bots?
But I agree that a group of paid astroturfers(/trolls?) who are writing different things, probably shouldn’t be called “bots”, even if they each use multiple accounts (provided that they aren’t semi-automatically saying the same things from the different accounts).
I do think that the concept of sock puppets probably captures much of the idea that “bots” is inappropriately extended to, and in a sense applies to many of the kinds of bots that people are talking about in this context (bots pretending to be many people, rather than a bot which is up-front about being a bot).
So, maybe talking about “socks” would be a good substitute for when some are talking about “bots” when they don’t really care if they are actually bots?
