It’s also the fact it’s just a summary of the post content without anything extra or any opinions.

Fair point

A decent way to classify human vs bot when it comes to dashes, is that all bots use ‘em-dashes(—), while almost none use regular dashes (-) in writing. While plenty of humans will use regular dashes, because they won’t bother to look for ‘em-dashes on the keyboard, or phone.

Of course, you have the people that correctly use em-dashes, too.

On iPhones the input methods turn -- into —. If you see me using em-dashes it's cause I wrote on an iPhone. But I prefer -- to —.

I've had it happen with various editors on the desktop as well. It's kind of annoying at times.
