Detection of "LLM" is a red herring. Quality is what matters. Always has been. Assess comment quality holistically, and you'll be fine.
We can consider this the carcinization of online discourse - everything evolves towards the optimum of LLM summarization.
Do you believe this?
But I suspect a lot of people on HN only view these threads as data and that for them "quality" only exists within the semantics and structure of the text itself, and the human element doesn't matter to them.
Just like any other behavior you don’t like.
[1] logically upvoting is also an option.
Drown it out with high quality submissions and high quality comments.
Smoke me a kipper i'll be back for breakfast.
No can do, too many false positives considering the usual demographics.
LLM detection is basically witchcraft, though, for all but the most obvious cases.
There's always been low effort comments and content, here and all over the internet. A decade or so ago people used to write comments like "this" a lot to farm upvotes off another popular comment.
In comparison to other places this kind of thing is largely discouraged and unrewarded on HN, although I have noticed the quality of comments here has decreased over the years and low-effort comments are definitely upvoted more often these days.
I guess we all just need to be more proactive in downvoting them when we see them.
