How much experience do you have interacting with LLM generated prose? The comment I replied to sets off so many red flags that I would be willing to stake a lot on it being completely LLM generated.
It's not just the em dashes - its the cadence, tone and structure of the whole comment.
Yeah it's really frustrating how often I see kneejerk rebuttals assuming others are solely basing it on presence of em-dashes. That's usually a secondary data point. The obvious tells are more often structure/cadence as you say and by far most importantly: a clear pattern of repeated similar "AI smell" comments in their history that make it 100% obvious.
