Nobody ever said that they were nonexistent before LLMs. When you are investigating and trying to determine if something is AI generated they are the number one indicator.

So if you're being accused of just spewing AI, then double down and spew what looks EVEN MORE like AI. What are you even doing?

Number one indicator? A single punctuation mark that's trivial to make on most keyboards (option-dash on macOS). And generally people who write software are extra fixated on punctuation for obvious reasons: missing semi-colons break your build, etc. Maybe in some other niche message board people will use dash and em dash interchangeably, but here?

Also, if the a single character is how you're red-flagging LLM output, do you know how easy it is to avoid? I didn't use it here at all, but how do you know I didn't run this through some slop-machine to tighten my prose? It's really low-effort take to say "just avoid em dashes so we know you're not an AI".
