Yeah, people do seem to think that em dashes are an indicator of GenAI. I have been accused of using AI to write my posts on a forum, precisely because of em dashes. That's how I found out about that particular sniff test people use.

Hasn't made me change the way I write, though. Especially because I never actually type an em dash character myself. Back when I started using computers, we only had ASCII, so I got used to writing with double dashes. Nowadays, a lot of software is smart enough to convert a double dash into an em dash. Discourse does that and that's how I ended up being accused of being an AI bot.

Shouldn't a double dash result in an en dash and only a triple in an em dash?
