It can be a good consideration but how one can recover the locked account if we want to move another location?
The account isn't locked because of him moving to another location; the account was locked because he tried to recover it through his Secret Question. You would know this if you had read the thread before posting for your signature.
BitcoinTalk doesn't care where you log in from, I have logged in using VPNs from all over the world and it has made no difference. Providing that you know your password/can recover your account via email there shouldn't be any problems.
