I will openly ask the question as to whether there are commercially available sets of contacts for you that they've acquired. Did you have them as FB, MySpace, or any other social network contacts ever? Or have you ever (if you can remember) installed any apps that had access to your contacts that long ago? Any company that acquired that relationship between you and these people may have been acquired or gone out of business and sold this info as an asset, all within their TOS.
