There is one very efficient way to thwart these big data collection attempts: build fake profiles and build fake networks. If everyone would use a little of his or her time to do this, it would be extremely difficult to find the real address or security number or phone number of a person. I foresee quite some opportunities for startups who would automate this. In this case not for "evil" purposes such as fake product reviews, or spam, but for - I would say - this ethically acceptable purpose of making it a tad harder to mine your personal information online.
