Clearly it is a public service. Doesn't everyone cross-reference their dates with these kinds of sites? I obviously wouldn't want to wind up with someone stupid enough to get their nude pics AND contact information on the internet.
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.
