A lot of anime are, inarguably, quite graphic. Many sport blood, open flesh wounds, nudity, and several other "mature" themes. Now, in order to effectively illustrate some answers, detailed written descriptions or images must be provided. [This is one such question](https://anime.stackexchange.com/q/2076/274), which contains graphic imagery of the aftereffects of severe bite wounds.

Do other StackExchange sites have policies on this? If so, what are they, and should we adhere to them? To what extent do we allow such images?
