What are deviantART's policies on nudity?

Submissions depicting nudity are allowed providing that the model is eighteen (18) years of age or older and providing that the image is not determined to be obscene or pornographic as detailed elsewhere in the FAQ.

All images containing nudity must be tagged as Mature Content upon submission. The deviantART staff reserves the right to mark any work with a general mature content tag if it is deemed by that staff member to require one.

We strongly recommend that photographers submitting photographs of nude models have signed model release form documentation on record. While providing model release forms is not mandatory the deviantART administration reserves the right to demand such documentation at any time and to remove any work for which it is demanded but not provided.

Photographs and other works depicting models under the legal age of eighteen (18) may be subject to restrictions.
