Signatures should not be intentionally sexually provocative: This means that any scenes of a blatant sexual nature are not permitted within signatures. Anything surpassing a mild sexual reference will be considered as being intentionally sexually provocative.
Signatures should not contain explicit nudity: Anything containing visual sexual organs, or bare breasts, are considered as explicit nudity. This is applicable to all mediums it is shown in such as scenes from games, anime, films, and anything containing a form pertaining physical nudity. The only exception is found within the Art & Design forum and is explained within the Art & Design rules.
Signatures should not contain violent scenes: Anything visibly harming oneself or another in a more than mildly graphic way would be considered a violent scene. The level of violence permitted is mild, anything malicious is not permitted. Themes of violence within signatures should not be very realistic, nor extreme.
