Either way, it would be a nice feature for an image service to help protect children who might fall into this crack. I think it's one of those things where legally you probably want to run a service like this as a carrier so that you don't get yourself in trouble by making mistakes. But as company that tries to be a good citizen in a society, I think you want to make it as difficult as possible for children to post NSFW images of themselves. I don't necessarily think of Verizon as a good corporate citizen most of the time, but I think it's completely reasonable for people in society to ask them to do so.
