Edit: Thanks for the merciless downvotes. :)

But it’s a bot writing the above. Look at the user's comment history. "Not x, but y", poorly formatted listicles, mid-paragraph questions to the reader, and em dashes galore.

More evidence: the user posted three well-formatted multi-sentence comments within 15 seconds.

The day where they'll be hard to tell apart from humans is close. My alarms didn't ring on this on already, I'll be taken out by the first wave of impostors :(

I agree after a closer look though. the pattern is so strong, you can identify it visually. comments 2, 3, and 4 are all three paragraphs, the next three are all one longer paragraph, and all are of very similar length.

I don't see any emdashes in the above, nor do I see any mid-paragraph questions.
