I enable the secret question pretty soon (probably during the account creation procedure), and later came to read that resorting to its use would indeed lock your account, being the unlocking procedure not immediate nor trivial. As such, I left the secret Q/A there, on the profiles, but often felt like I really wanted to delete it (having a signed message on the appropriate thread seemed more fitting). It took me ages to delete it, but it’s really rather trivial:

Locking the account after doing the forgot password method with a Secret Question is intended so that the person doesn't easily open the account. -snip-
Just imagine if a scammer who knows about the secret quest that we have previously set up, locks the account to further secure the account itself.
The impact of being locked into an account will be uncomfortable when the user does it himself. To try to open a locked account I created another account and contacted the moderator via PM Bitcointalk and also contacted the bitcointalk recovery team via email. I can open my account in just a few hours.
ACCOUNT LOCKED FIX PROBLEM
I sent a message to the email that was printed when the account was locked and the bitcointalk recovery team responded well.
I was going to ask on why enabling secret question wasn't a good idea 'cause it confused me (when it was designed to help you for retrieving your account password), and then I see this. Thanks for the input though. I was wondering few days ago if I should make one for myself but I think, I should withdraw from doing it so now

You are better off avoiding activating Secret Questions and using other security..In order for you to prove that the account is your account, you need to do SIGNED MESSAGE BITCOIN ADDRESS, as DdmrDdmr
