Isn't the option to recover your password by answering a secret question disabled on the forum? I'm not sure, but I think I read somewhere that if you try to recover your password that way, your account will be locked and you will have to request a manual review and recovery process. (I can't find any details about it now though.)
It is not disabled, but yes your account will be locked if you try to recover an account with the secret question feauture, i honestly think it should be completely disabled, and members should not be able to set it, because, 1)it is not recommended and a bad idea of a second password, 2)it can be of no help, since even if you forget your password, and you want to use it for recovery, the account will be locked, 3)members should stick to recovering their password only with their email address, that way they should remember to use a valid email, and keep it safe. Here is some details about it:
This is a Public Service Announcement:
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.
