Re: Please Help: "For security, your account has been locked"

Could this be due to reinstalling Windows?

I'm pretty sure this is not the reason. Did you try using your account Secret Question?

What can I do to unban me? Help me please.

Follow this thread to unlock and recover your account: Recovering hacked/lost accounts

No, I did not use the Secret Question.

For me, this option is not suitable, I do not have a bitcoin address.
