https://www.sligocki.com/ hasn't posted since April, and the very first link on that blog is a link to... Scott Aaronson.
I spent 5 minutes trying to verify any link in the post above links to Scott Aaronson, or mentions him, and found nothing. :\ (both the siglocki, and when I found nothing there, the busy beaver site)
"One Collatz Coincidence", the 2nd story on the blog, also mentions Aaronson
