But... why?
It begs the question: *why* do they want so much data? I don't have a Facebook account, and I've never been contacted by them, and any advertising I've suffered (which is partially Google too) has either been absolutely irrelevant or something I've just looked at - which I don't see why they'd need my details for.
Is it just that there are some data fetishists at Facebook who collect data for its own sake?
