Posting someone's facebook profile is the same as posting his first and third name, plus his birthday date, plus his adress, plus whatever else can be seen on the facebook page. So I think you should change that.
It's like saying that it's not allowed to write down someone's age, but it's okay if you write down his year + month + day of birth, as long as he doesn't ask anyone to remove the post.
Tell me if you are going to do something about my avatar's pic, I am going to settle all by PMs.
And if you can't prove this facebook isn't mine (or has anything to do with me), you can't post it. Or you can, but then have it removed on my request. Or whatever.
