Thread: How Does This Work?

I bet if I was able to ask FB they most probably have no idea how it happened either because they release the software to do its thing and it does it, very frightening when you think about it all hence my refusal to get involved any more than I am.

that gives some clues.
Mrs P. will be friends with Miss P. which means that everyone who is also "friends" with Miss P know that Miss and Mrs P are friends.
I'm not sure how many generations of friendship this cascades to but you should get an idea of how the web of "friendship" extends.
If Mrs P has "liked" a post by Miss P that contains an external link, then the scope for linking starts to become endless.
