I think things like Blackmail Photos (and possibly fashion-based props) would work better as Assessments/Declarations of preparations they have made (using Investigation, Resources, Presence, etc.) which give the players Aspects (on themselves or on the target) which they can Compel/Invoke/Invoke for Effect.
Social Items may be better suited as enchanted items of jewelry, special ties or tie-pins, etc.. set up with particular bonuses. Though there is nothing saying you can't enchant a camera to be unusually good at taking photographs, giving a bonus to any Assessments using the Investigation skill.
