|Description:||Similarly to how posts have explicit, questionable, and safe ratings, it might be useful for avatars to have ratings as well. This way, a user in safe-only mode who decides to visit the forums or look at a user's profile won't get shown porn anyway.|
The rating could simply be a required field in the upload box. It would be useful for site staff (including gardeners) to be able to change the rating of the avatar. It might also be useful for users to change the rating of their own and other people's avatars after uploading.
