Well the "Uncensored" CG art you see in Pay sites. (Usually these pictures are stolen from simple adult PC sim games) have the genitals re-drawn in (Often poorly) by whoever hosts the pics. In the west anime, manga and games that are brought over can use footage without the mosaic censorship... asuming the censorship wasn't drawn in. (I remember My friends and I getting a good laugh at the "Lightsaber penises" in this one show we were watching at a con.)
