I still have full control of this address, and I create sign message using the address
Address:
15obAnwwEKxVSFJkqqn5NXHpZhAznZXUeY
Message:
hello everybody. this is the real owner Falconer account
Signature:
IOLh0KLv0cy9ZG8qzHq0JoA/2VxN/gOuRUaiIg7j9iwBSeHKns8SzmOXPzoX/zUcjNvgvQ9gk8nCU5PWj/oLXko=
To be thorough: can you add the date to the signed message, and say "falconerhacked is my alt account"? The current signed message could have been created by the real account owner years ago.
exact
I thought the same thing, if you don't add the date this message doesnt make any sense
it could be a signed message that you stole some time ago
If you have the address, signing another message shouldn't be too complicated
