Hold on, I'm coming back to this thread, I think I've cracked it guys. Some real alpha for you right here: If the em dash has spaces around it -- as seen in AP style -- it was probably written by a real human, because that's how it comes out most conveniently on a word processor. But if the em dash has no spaces around it--Chicago style--there's a good chance you're looking at LLM slop.
