kenwas's recent image was approved as the 'nudity' was particularly small/insignificant....and was not what is referred to as 'full-frontal'...that needs must include male/female genital areas. Breasts in themselves constitute 'topless', not 'full-frontal'.
There are other depictions of varying degrees of 'nudity' in the wall section, but none is/has been deemed 'pornographic' by those whose responsibility is to moderate site content. The walls that end up on the 'cutting-room floor' that do not see the light of day here are very definitely not suitable and are clear candidates for removal.
Wincustomize.com is a better place for all thanks to this moderation...
