LJ has a few problems lately.  You may have heard about LJ deleting journals.  And outages.  As a side effect I've noticed when I lock a post it doesn't stay locked.  Last month I had to lock a post literally three times.  It finally appears to have stayed locked.   I'd been somewhat distracted and LJ had yet more problems and it appears to have happened with a recent post.   I apologize to those who read the post and thought it was public.  It was not meant to be.

I used to work in computer security so I tend to think no lock is secure and even in my locked posts I don't use RL names unless the person has given me permission or it's a matter of public record.  Even so it's annoying because I lock posts so people know what I'm writing is meant to be private.
