If you lose your password, DO NOT USE THE SECRET QUESTION TO RECOVER THE ACCOUNT. It will result in your account being locked. Please use the email recovery option to recover the account.
The reason that the accounts are locked is because the May 2015 hack leaked Bitcointalk's database which did not securely secure the Secret Question and Answer. To prevent people from guessing the answers, theymos made it so that accounts that are recovered using the secret question are automatically locked when the option is attempted. This is to prevent hackers who may be able to guess the answers from the leaked database.

Maybe some staff member will see this message,or maybe someone know,who from staff members is working with issues like this?

Read and follow the steps from this sticky thread: Recovering hacked accounts or accounts with lost passwords

Take note: Recovering accounts, take a very long time (not a priority for admins).
