This is a most excellent place for technology news and articles.
Maybe I'm I don't have enough of a technical understanding (and I'm wrong about this) but I believe there is some sort of fingerprint at the OS level (not IP or Mac) that they can obtain when you're on the net that in turn they want to map to your identity, thus even if you're using tor/vpns to mask your IP, you're still identifiable.
