Just got a few recommendations by my colleagues on LinkedIn that were clearly written by an LLM, the long emdash was even present. But then again, the message was tuned to specific things I did. Also they were from Eastern Europe, so I imagine they just fixed their input.
If you call yourself a writer, having tell tale LLM signs is bad. But for people who's work doesn't involve having a personal voice in written language, it might help them getting them to express things in a better way than before.
