I'm being serious here: Looking for em-dashes is a terrible way to "scan" for slop. You need to look deeper than that and if you did, there's clearly a voice there. If you let yourself develop an "em-dash allergy" and think this helps you avoid LLM-slop, you're scanning for the wrong things and it's going to do the opposite for you. Actually stay on your toes and don't become this complacent.
