Unfortunately most of what gets posted to HN or could conceivably be posted here is already LLM generated to some degree. Because content of interest to HN tends to be written by the same people who increasingly prefer to use an LLM for everything they do, machine-generated submissions are only going to increase over time. Tagging submissions as LLM generated is ultimately futile, as one might as well tag water as wet.

Also HN's design ethos of not having "silos" precludes having tags or filters or blocklists, since they want everyone to see the same content at the same time. This is the kind of thing you're going to have to use with a browser plugin or third party service if you want it at all.

Or they could...just use Reddit or Lobsters, it's so weird that they want to fight the whole purpose of this site.
