What is brickblock.io? I have javascript disabled and the website wouldn't load for me. Let me guess, it's another ICO scam that asked for your Bitcointalk username and password somehow? Have you entered your pass somewhere else? You may have been victim of phising. If that is the case, then it's not Bitcointalk's fault.

In any case there are a ton of people getting hacked lately... another database hack with accounts being sold out there? who knows. If you have a BTC address that you posted before the hack, you will be able to recover the account with a signed message, I doubt you can get it back any other way.
