Ask HN: How do we handle the rise of low quality "This is LLM" comments?

It has become a proxy for "I don't like this article, so it must be a LLM"

To me, it feels like lazy karma farming, as these comments often do get a few upvotes.

And of course, accuse a 100 posts if being LLM, you are guaranteed to be right at least once, then like astrologers you can claim success.

Is there anything we can do to discourage this type of lazy and low effort posting?
