Asked mum and dad and they're all cool with telling people where they live. I live with them anyway.

Every time someone on FB shares a picture with other people in it they are doing just that.

> So their selling other people's data too?

I was answering that particular question. Either you didn't get it or you pretended to not get it, hard to tell the difference from here.

Well, yes. Say you tag a friend in a photo at a political fundraiser, protest, etc. Or you tag them posing by their company's logo, or at a booth their company is running at a trade show. The context of a photo matters, and FB can extract an awful lot of information out of seemingly-innocuous things these days.

So crazy it just might work
