This account has changed hands. My 3 accounts have been taken by my friend by cheating me. I want justice for this.
Ask those who are using my accounts to sign the address message. If they can sign the address message, then I will never come to this forum again.
If your account was stolen as you claim, then why don't you go through the account recovery process to have it recovered?
Recovering hacked/lost accountsYou will need at least access to an original email address that the account was registered to and if possible a signed message from an old address you used before the said hack or stealing.
