FWIW this part of your comment does look generated by Claude:
> I'm seeing a worrying trend on HN. Nearly for all articles, there is one unquantified, unproven comment at the top saying it's 100% AI — no proof, just baseless emotion of what fits the commenter's writing style. This is the new witch hunt, or virtue trolling.
Was that the case? Genuine question. Here the em dash is an actual em dash symbol, where in the other paragraph you used what looks like a minus symbol. It’s also the type of construct used by Claude.
