Wild idea: Could be a symbolic dead man switch.

Reports of FBI going hard after archive.today around the time the HN account was setup and they post an archive.today competitor. Pings on the investigative article then a post to HN saying “3 days ago” which could indicate when FBI succeeded.

The only comment by the poster on this article is a sharp clarification of what doxxing is and isn’t.

Perhaps this is just an unusual way of slowly stepping out from behind the curtain on your own quirky terms after a fantastically long tenure.
