Technical question: does anyone know if FB can easily answer why X was recommended to Y? That is, do they have to manually check or can they query this easily and get the precise answer why a recommendation was presented(for example: the reason why X was recommended to Y on date d, cannot be that X is connected to Z and and Z to Y, if X connect to Z on d+1; I assume bad inferences like this will probably happen often if such questions are answered manually).
