Those are comment repaste bots.

They look for highly voted comments which typically have more upvotes than the comment they are responding to, but they're stuck under an ultimate grandparent comment which isn't the highest voted comment, and then the bot posts that comment in the comment chain under the top comment trying to farm karma.

They're now truncating the comment so it isn't a perfect match, which often results in "am i having a stroke?" comments under it as they mangle it.

I guess you do that and even if 99 accounts get banned the 1 account that gets a pile of karma can be sold off to social media companies / troll farms to push whatever their agenda is.
