> Em-dash (—) is COMPLETELY banned. It is the LLM's signature stylistic crutch and it is the #1 visual Tell in production tests. There is no "limited use" allowance, no "natural language frequency" allowance, no "in body copy is fine" allowance. None. I guess the em dash is really dead.
Probably not, because now you'll have all of the people who are worried about this ensuring their AI generated text never ever uses em-dashes, and then that will be the new tell. Or we can just be more concerned with whether something is well written and well presented and accept that sometimes that is going to be AI written text.
I guess that's kind of my duress code :)
