From the beginning, I’ve noted Facebook photos are mostly young females, well-dressed, usually with alcohol.
You KNOW this is going to cause grief long-term.
There’s very little anonymity on Facebook. Once something is posted, you cannot DELETE easily. It’s been backed-up somewhere.
Why do young women participate when it’s clear photos like this — and worse — will eventual published. (By their “friends”.)

I’m relieved we didn’t have Facebook when I was her age.
One opinion:
“People are perfectly happy to post these sorts of pictures because they recognise that alcohol-related embarrassment will actually improve their social standing.”

Obviously social networking is a winner. But I hope Google steps back to see how to do it with privacy and security in place by default.
