Not just better education around security practices, but better understanding around control of your content, where it's stored, what happens to content when you press that button in an app. I don't want to victim blame here, and this guy is a total creep, but the victims uploaded their nudes to the Internet. At that point, the cat was out of the bag.
Part safely using the Internet is having the knowledge and being aware of where (in your apps) the boundary is between your local device and the global network that everyone has access to. People need to understand: When you sync to a cloud service, you're sending your content to someone's computer unknown to you. Yes, in this case, it's Apple's computer, but that didn't stop this guy. Once you sync something online, it's out of your hands, and on the Internet now.
I personally treat all cloud services as if they were accessible publicly and anonymously, and will inevitably be printed in my local newspaper, and only upload content to those services where I am comfortable with that level of exposure.
EDIT: To clarify, I wish applications would stop blurring the line between "on my device" and "on the Internet". I've used applications where, to an unsophisticated user, the save dialog looks like it's saving to their computer but it's actually in the cloud. Add to it all these apps that try to be helpful by seamlessly (and invisibly) keeping local content in sync with the cloud versions and you have a recipe for disasters like this. Have an explicit "upload this thing to the Internet" button, please!
It boggles my mind that people have nudes of themselves on any digital medium. I say if you want to dabble in that, get a film camera and develop the pictures in your own basement.
Or get a non-wifi digital camera and manage your photos on a non cloudy computer. Maybe even take it a step further and use tools to remove EXIF data that has your camera's serial number and other metadata in the images. Photos taken from cell phones often give away GPS coordinates.
