People put themselves, plus pictures of friends, family and strangers, all over facebook. I think most people don’t even bother asking permission or turning “safeguards” on. I think bad actors can find your information these days without too much trouble, regardless of the security measures that have been taken. I don’t disagree with being cautious, but I think I think the relative risk is a bit overblown because it’s all already out there to be found. It reminds me of the hours my Mom spends putting black magic marker over her address on all of her junk mail before she throws it away.
