The claim "written by AI" is not really substantiated here, and as someone who's been accused of submitting AI-generated content repeatedly recently, while that was all honestly stuff I wrote myself (hey, what can I say? I just like EM-dashes...), I sort-of sympathize?

Yes, AI slop is an issue. But throwing more AI at detecting this, and most importantly, not weighing that detection properly, is an even bigger problem.

And, HN-wise, "this seems like AI" seems like a very good inclusion in the "things not to complain about" FAQ. Address the idea, not the form of the message, and if it's obviously slop (or SEO, or self-promotion), just downvote (or ignore) and move on...
