Sealed Lock Doesn't Work?

I hope that isn't true, otherwise the hacker would ticket Nexon and the lock would be gone.... then the item is theirs.

This is exactly what i was thinking, once the "hacker" has your account they are you. So it will be easy for them to send in a request on unlocking the item.

This is were nexon needs to add a new batch of secret questions, when you file a ticket to unlock your item include 2/4 right secret answers.
