It wouldn&#x27;t surprise me if Facebook created profiles for people who&#x27;ve never used it, just by virtue of having enough of their friends having their contact details.   IE if 5 people are friends and all have &quot;fred bloggs&quot; in their contact list then there&#x27;s a good chance it&#x27;s the same &quot;fred bloggs&quot;.  I&#x27;m not sure what this virtual person is worth to advertisers, though, just like I&#x27;m not sure what you&#x27;re worth if you don&#x27;t use it any more.
