I love em dashes too! I won't stop using them and I don't know why people see them as a marker for AI. 

The second comment is also AI, and I simply changed the prompt to get it to do that. That's why it's impossible to actually accuse someone - it's getting impossible to tell. Anyone accusing wants to be damn sure. 

I love the way some uni professors say they can tell it's AI because idiot students leave the prompt attached 😂😂
