I think what makes the em dash seem AI-like is… there isnt an em dash button on the keyboard.

So typically the only way those show up is when markdown-to-blog-post tools convert normal dashes into stylized em dashes as a transpiling process.

Stuff like hugo and etc largely do this automatically.

So if a poster uses an em dash out of that context, it right away throws up a red flag cuz… howd you do that easily?

Did you memorize the alt code to make one?

This looks completely normal to me, nothing about this appears to be AI.
