Maybe you would have more success when you would sign a known bitcoin address of yours from long ago. That would show that you still are the same one owning that legendary account.
You know... people on here are very cautious now when they read about the problems with Maidak.
I question this belief. I could prove today that I own a bitcoin address from 2011 and tomorrow I can go and sell my account and my trust. In my eyes a person who sells his account is a scammer. I will never sell my account for that reason. You see what I'm getting at? There is no difference between suddenly turning into a scammer and selling your account.
Now I was running an exchange which held several hundred thousand dollars worth on behalf of customers as late as 2014. Connected to this account. And I can prove that I still own the domain of which the exchange operated.

And you know what, I'll see if I can get my 2011 bitcoin wallet booted up as well and sign an address, why not
One thing I should do, is setup a PGP identity.
