Everytime this subject comes up folk reply saying "I browse r'soity at work", here's a suggestion that I follow while I'm at college - avoid the poser galleries completely! Check them when you're at home. While nudity flags should be used according to the TOS half the time they aren't. While there is the responsibility of the artist, there is also the responsibility of the viewer. As has been said already if you don't want your kiddie to see "rude" bits then don't surf the site while they are about. It's a two way street, and application of common sense.
