Have you signed messages with the same address what was asked by the forum recoveries teams? I don't think they will lock your account even if you sign the correct message.
By the way, why don't you mentioned the profile of yours and also the wallet address with the message sign? I think it will increase the possibility.
He just said he has signed a message and left messages to theymos and Cyrus and no response yet, as we all know Cyrus is part of the recovery team.
OP If the messages are not from the original account email you're wasting your time that's how it works. Sending PM on the forum is waste of time.
