Perhaps it would be better to have comments that praise apparently human-written text?

I understand where you're coming from. I've been posting complaints about LLM-written articles almost as long as I've been here. (My analysis is definitely more complex than a search for blacklisted Unicode characters or words.)

But I've let off on that, partly because I agree the guideline is meant to encompass that kind of criticism (same with my comments about initial page content not rendering with JavaScript, honestly) but largely because it just seems futile. It's better material for a blog post than HN comments (and would be less repetitive).
