On a related note, I overheard two college students talking about why they change clothing in the bathroom stall of the women’s locker room at the University’s PE building.

The reason was that they are afraid somebody will surreptitiously snap photographs of them while they are undressed, and then distribute the pictures. Apparently they know someone this happened to.
