The point being, be VERY careful when speculating about a model's age. You probably are clueless, especially if, unlike people like me, you are not regularly comparing a girl's appearance with ID documentation.
People don't appear a particular age, they appear to be a range of ages ("she could be anywhere from 15-20").
CP is a serious matter, and accusations should not be made in publid without facts in hand.
