stolen?
Certainly not. I can prove the account is mine with signed GPG message whose key will match a message posted with the account months ago.
only months ago? Can you prove you own it since its beginning? Or you bought it?
My bad, I didn't check the date properly. My GPG-signed message was posted about a year and 4 months ago. I can verify my ownership of it in other ways, including the account's listed bitcoin address that I am able to prove I control. Was pretty active in the beginning. I used my GPG identity a lot on the bitcoin IRC scene, I have friends there who will confirm that I've been around a long time, and will do so in a live chat session if you're on IRC.
