ESRB Content Descriptors
The ESRB (Entertainment Software Rating Board) has a rating system very similar to ANN (in fact it's very possible the ANN system was based on it) but in addition they have a predefined set of 'Content Descriptors' to further describe the content of a product. It would be nice if we could use those same descriptors in the 'Contains' field of ANN reviews:
Blood - Depictions of blood.
Blood and Gore - Depictions of blood or the mutilation of body parts.
Comic Mischief - Scenes depicting slapstick or gross vulgar humor.
Gambling - Betting like behavior.
Mature Sexual Themes - Provocative material, possibly including partial nudity.
Mild Language - Mild references to profanity, sexuality, violence, alcohol, or drug use.
Mild Violence - Mild scenes depicting characters in unsafe and/or violent situations.
Nudity - Graphic or prolonged depictions of nudity.
Partial Nudity - Brief and mild depictions of nudity.
Strong Language - Profanity and explicit references to sexuality, violence, alcohol, or drug use.
Strong Sexual Content - Graphic depiction of sexual behavior, possibly including nudity.
Suggestive Themes - Mild provocative references or materials.
Use of Drugs - Use of drugs in a manner that condones or glorifies their use.
Violence - Scenes involving aggressive conflict.
Other MSRB Content Descriptors are less likely to be useful for anime:
Edutainment - Content of product provides user with specific skills development or reinforcement learning within an entertainment setting. Skill development is an integral part of product.
Informational - Overall content of product contains data, facts, resource information, reference materials or instructional text.
Mild Lyrics - Mild references to profanity, sexuality, violence, alcohol, or drug use in music.
Strong Lyrics - Profanity and explicit references to sex, violence, alcohol, or drug use in music.
Some Adult Assistance May Be Needed - Early Childhood Descriptor only.
Use of Tobacco and/or Use of Alcohol - Use of tobacco and/or alcohol in a manner that condones or glorifies their use.
