I don't think cm0002 is a bot. From what I remember, cm0002 makes a lot of posts to grow various communities, some of which are crossposts in between communities with similar topics. Although this account looks different from the one I remember, so maybe this one is an alt.

I personally don't find that behaviour to be harmful unless it's fully automated or a fire hose of low quality junk. If a human is picking out the content to post, then it gives people something to discuss and vote on.

I'm likely biased myself since I also schedule out posts with another account @otters_raft@lemmy.ca. I do that since this account is an admin account, and so I don't want to risk any issues if the scheduling tool goes haywire. I do check it about once a day and respond to comments when appropriate, but overall the post to comment ratio on that account is pretty lopsided.

We DO get harmful bots too, and they get downvoted/reported/banned very quickly. Those are pretty obvious since they post spam and ads in unrelated communities.
