A much better approach would just be to write a email or add a entry on a Blog, with proof of a signed messaged to his/her coins.
As someone who was here early on (when Satoshi was on this forum) I do occasionally receive requests for historical information ...
Example:
« Sent to: BitcoinFX on: August 15, 2017, 08:44:15 PM »
"Hello,
I am developing a website dedicated to the history of bitcoin. I noticed you are an early user of bitcoin, and was wondering if you had any e-mail conversations with Satoshi or other early developers that you would be willing to share? If requested, I will remove any of your personal information before making anything public.
I am also interested in any IRC bitcoin or bitcoin-dev logs (pre-2011).
Thank you for your time!"
...
Satoshi - If you recall, can you tell me what you told me you wanted to build for Bitcoin, before I also left this forum?
P.S. Do send me a PM for my protonmail account and yes I ofc have a 2nd 'authenticator' question ready, if you know the first answer.
Bitcoin Bank

seems like nearly everyone forgot what bitcoin was about
Can we use the Bank?
