I am more than happy to forward the email from bitcointalk to anyone who would like to verify. The wallet addresses provided by me are from two three years before. I have no control over them now. But admins from Stake signature campaigns can vouch for me as I am still in contact with them.

The above message is posted by the hacker.

Note: He has no access of my phone. My email and facebook account got hacked after I tried to install a pirated software on my computer from torrent. Once he changed password of my facebook account I got the notification and locked it. For Bitcointalk he knew that I would get the notification when he change password. So, he sent a signed wallet address on another thread and quoted some posts like the one mentioned above then changed password the next day.

I have already done that. It is locked but does he able to claim the account just because he provided a BTC signed message signature in this thread. I am not able to provide one as I believe the provided wallet addresses of mine are deposit addresses for crypto exchanges. I have never shared my personal wallet on bitcointalk.

That was two three years before, mostly they are crypto exchange deposit addresses which I have no control of. I believe, I have never given my personal wallet address anywhere. Anyway, even if I don't get my account back, I don't want him to use my account and post on my behalf.

My email was compromised two months before. Somehow, I retrieved it and put 2FA. But, I forgot to change the password of bitcointalk forum which had the same password. I think this is the same one who hacked my email.
By Stake affiliate link I meant, the signature my account has. It is a crypto gambling website named Stake.com.

This guy is a hacker. Please give negative trust to this account. I am the  owner of this account and he changed email address signature affiliate code and Bitcoin wallet address today.

This guy is a Hacker. He just changed my email address and wallet address. He even replaced my Stake affiliate link with another one. I locked this account already but, I don't know whether he is able to recover the account with this signed message.
