I guess my point was lost.

It is obvious, when it is obvious. When it is not, you don't know it.

There are ton more false positives now. Everyone is calling everything 'LLM Slop'.

Because there is a lot of slop. Now every bad human writer is being called an AI just for being human.

And, that is covering that a ton of stuff is LLM and nobody can tell.

People that say they can tell the difference are fooling themselves.

Don't beat yourself over it. It's the new sport for HN upvote farmers to default to calling out any TLDR post that got "delve" in it or some other cliché as LLM Slop. I also think it's a waste of time. What's important is the content. Is the content of the article valuable? No? Just close it and move on. But we know the incentives to get a few upvotes is just much too good to pass...
