Hello all, 
I opened recently a new account at FB and I checked how it propose new
friends. It started from the very first friend search I did by proposing
friends of people related to people I searched for. This search was
recorded, not only as a cookie but in their systems as I erased all the
cookies and FB kept proposing new friends.
One of the "devious ways accessing private information" might be the search

It may have been that it initially scanned based on very basic information
like last name and current city. First wave may have then included ppl like
the mother and father. In subsequent algorithms it may have scanned those
identified in first wave for shared friends- so it possibly identified the
granduncle based on information like the mother and father (etc) have this
shared friend, the granduncle. Hence, these ppl get suggested as possible
friends in a shared network. 

Plus, FB is known for devious ways around accessing private information.

That's my educated, non-expert guess. 


Out beyond ideas of wrong-doing and right-doing, there is a field. I will
