I think at this point, given that both Android and IOS make giving apps access to your contact list easy, you are in fact in these sorts of graph databases in a couple dozen organizations by now, courtesy of people you know.

Pokemon Go, Skype (now Microsoft), Whatsapp, Snapchat, Line & WeChat if you live in Asia, Path, Yelp, Twitter, ... all the bigger internet companies [1]

And sadly there's the really cheesy ones like "Fantasy War Tactics" [2]. How many of your friends play that sort of crap ?
