its really not, I don't know what that guy is talking about. Its actually quite easy to create fake profiles, and fake networks, and add friends that would match that information.
It would take you a really long time to fake a profile - and it would take an extended amount of effort. Unless you have a specific target in mind, how easy is it, really, to create a credible network of 300+ friends?
In any case, I will bet you $1.14 USD that I can find a credit card number faster than you can generate a facebook profile that's credible.
