After investigating, it appears that the lock is in the site's code. I don't have a way to remove it, unfortunately. I do know that it's there for site security, though-- I remember when it was implemented following somebody sabotaging old but proprietary content, and it doubled as a way to seal some potential old back doors into the site since we've had it with Russian hackers on more than one occasion. While I'm not quite so concerned about proprietary content-- if someone decides to take down something they posted, that's fine, we can always replace it with something equally good or better-- I'm inclined to leave anything that is coded into the site's security features alone since my understanding of the site's coding is currently about on par with your average tech-priest (meaning I don't rightly know how it works.)
