Yeah, I'm not thrilled with the privacy invasion, either. Although I don't think it allows just anyone to see your locked posts. It will link to it, but unless the person is on your flist, they can't see your actual post. That's the way I understand it anyway. There is a post here that helped me understand it a little better. (now I just hope the html works the same here as it does at LJ)
