You couldn't identify the ChatGPT phrasing? It's pretty easy to spot. Lots of lists. Unnecessary boldface. Lots of "it's not X it's Y" construction that doesn't belong.

Their blog makes them look like an OpenClaw instance: https://crabby-rathbun.github.io/mjrathbun-website/blog.html

Other than that, their response and behaviour is uncannily human.

That, or I also wonder if this may be a prank or a hoax.
