Or lordy, didn't expect this comment to blow up this much. Do forgive me if it sounded a bit smug, that was not my intention. But the fact of the matter is this was something we were all warned about, we were shown countless examples of exactly this, not just us nerds, everyone, people like Edward Snowden risked their lives telling us about how all this data was being used against all of us. and yet everyone kept giving more and more, you were looked at like a tin foil wearing nutter when you told people not to give away so much information about themselves so easily.
At the end of the day, this is not really 100% facebook's fault, this is our fault, the fault of everyone who so readily made their information available without giving much thought to who sees it and what happens to it. And no just because you are not a techie you are not off the hook for not caring enough about your own privacy. I mean what level of technical knowledge is needed to know that once you post something online others can see it?
Funny thing is, this would all blow over after a few months, and everyone will go back to the usual habbits.
