What I want to know about this thing is...where did the people who posted the naky female marines get the pictures?

you'd think every human on earth from age 5 on up would know by now...if you take a naky pic of self and/or have one taken there's a high probability that it will find it's way to the internet.

I'm pretty sure the marines don't make recruits strip naked and then take a picture of them. So where do the nudies come from?
