If you don't know, Satoshi Nakamoto used to post his real name and address in Bitcointalk.
1, 2, and 4 exist in the staff forum. 3 was permanently deleted at some point (it must have contained Satoshi's real name and address).
If Satoshi himself posted his real name and address on a public forum within the community, that means someone here still knows who he is and if he is still alive or not.
What if the guy in the comment section of the reddit post, the one who consider himself OG member of the forum, knows that Nick is Satoshi? Kinda interesting tbh.
