Google Earth Zoo

I’m not sure what to make of Google Earth Zoo. On the surface it looks aimed at schoolchildren, providing them an original pretext to learn how to use Google Earth’s interface. But if you click on “Toilets” you get a gallery of images that are certainly NSFS (not safe for school). Are these slipping by naive site admins? Do the site admins themselves think these are funny? (Hint: goatse is not a random name).
