Two of the girls were underage when the pics were taken. Bear that in mind if you are still looking for them. That is also going to hang a world of hurt onto the people involved given US authorities will almost certainly try to hang child porn charges on them.
Speaking of the people involved, a couple potential suspects. Including one genius outed by 4chan who claims to be innocent of the hacks, but instead was only trying to scam 4chan for money. Guess how well that worked out for him?
