I have expressly told all of my children and my friends that I do not want my face plastered on Facebook! Not that I am ashamed of it, I am just as ordinary as anyone else, but I did get pestered by a couple of men when I originally joined so I got freaked out with that.
Also I don't think you should tell your dil what she puts on her page as that is up to her. I don't like the way people put children's pictures on there because it is not safe. If not protected with security they can be clipped/snipped/copied and altered by weird people for their own ends.
In any case, for me, Facebook is now a no, no. My son who looks after my computer problems for me had an awful job getting rid of some malwear that had come from Facebook so I am banned from going on there unless I want to lose my very good administrator, which I don't. He is very good, always willing to spend his spare time sorting out our problems, but he cannot keep bailing us out all the time as he things of his own to sort out, so I don't blame him.
