Also given how many people use IPhones, how many pictures they have and how often they have many similar pictures, thinks are not necessary that simple. I wouldn't be surprised if some flat, small height fully adult (e.g. 30) woman does some sexting and goes from 0 to >40 collisions in a month. Not because of arbitrary collisions but because the similarity some of here sexting pictures might have with the ones from a 14y old but older looking girl (which e.g. where forced and ended up in the database).
