The following is my original April 15, 2018 post, signed using my account's signing address (https://bitcointalk.org/index.php?topic=996318.msg55749015#msg55749015):

You're linking to a signing address you posted today, which doesn't prove anything. Can you sign a message from an old address like this one: 1P1nsECBk5HoSJeQVNdsarpAybz1LHrs1X (linked to this post: https://bitcointalk.org/index.php?topic=1687999.msg17041076#msg17041076)

That's a good suggestion, but I can't find the wallet used to send the bitcoins in that specific transaction. However, I can sign a message using an address from an earlier transaction:
