This comment has become more robotic than the thing it criticises. People use em-dashes and emoji all the time! They are easy to type. On Apple operating systems you can even make em-dashes accidentally by default by simply using two hyphens. Those by themselves aren’t sufficient to detect LLM writing, please stop propagating that wrong idea. And emoji?! Human communication over the internet is littered with them, they’re insanely popular and have their own jargon and innuendos.
