I grabbed the data and found an old peer in there, and he listed both our office and his home address in profiles, which he would never have done for anything else. He also used an email address on a domain he controls that he created just for that, and accessed it (there are IP addresses) from a remote corporate location while on a trip there (I actually was on the same trip with him).

This is just one record, but that data is absolutely real. And I looked up this particular person because they struck me as exactly the userbase of the site.
