Having found one I looked through the Ratings and Advisory Policy on labels an artist should have on their work, and after getting past the expected Nudity, Sexual Content, and the like, I reached this -
Racism refers to the depiction of racist themes, bigorty, or hatred from one race to another. This applies both to the picture itself as well as any views put forth by the artist in their description. Mild - May depict symbols or objects commonly associated with racist themes (such as a Nazi swastika or the so-called "Rebel Flag"). Moderate - May include depictions of racist acts not including actual violence. High - For depictions of actual racist violence.
The next label was for Spoilers.
