I'm sitting here wondering what possible motivation someone might have for running a site like Pinkmeth. It's one thing to share the amateur porn, but why share the names and locations?
Either that or someone is just attempting to facilitate trolling/being a dick.
Nude pics can get online through a stolen phone, lost phone or a breached account of some sort. Once you have a picture of someones face it's pretty easy to get a name through the right channels.
