Yes, FB contains an element of trust because, for me, I've posted my pictures and where and when I've gone to school. I think I faked my birthday a few days but I'll check to make sure. Birthdays matched with names might be sensitive for ID theft reasons. Also, if you here know me from FB, then you know I'm an XJW. Thankfully, no one has outed me there. That is trust being proven. Thank you!
Edit to add: Addresses matched with names are no big deal at all because the phonebook contains thousands. Mail anything and your address would most likely be on it.
