Apparently, this user prefers to keep an air of mystery about them. Perhaps because that opens up an infinite range of exciting possibilities. They could be Elon Musk. The guy who invented nerf guns. A visiting time-traveller trying to get you to fix your analyses to stop the impending disaster. Or a random postdoc who knows a tiny bit about stats and is somehow using it to procrastinate about their real work. Could be any of those. I guess you'll never know.
