go to Profile>edit Profile...

once there, you will see tabs up on the left hand side that state such things like 'gallery', 'following', etc....

click the tab marked 'gallery'... there will be four boxes that define options: 3 that govern language, nudity & violence, and one that governs whether you're open to receive ebots to your preferred email address whenst someone you are following posts an image. if the nudity option is checked, then nudity is being filtered out from your view.. if that box is unticked, then something else is going on....
