A signed message from an old bitcoin address is a standard procedure to prove that the account belongs to me.
I would not know how else I could verify my account. I can talk to you in German if it helps you (just kidding
).
As I said, this account has never changed the owner and will never change the owner!

A signed message is a way of retrieving a hacked account. They can hack your forum account but not your Bitcoin private keys. There is no way of proving account sales one way or the other because the seller can provide everything you need. I'm not accusing you, I'm just pointing out that it's not something that can be proved.
