Jappy, we have already explained how visual effects are harder to censor around little kids than audio elements. Things like Ass Up! should have a warning for audio, because of obvious lyrics that are inappropriate. It seems like you are trying to defend the video elements instead of trying to come to a conclusion about what warrants an audio warning, something most of the staff that are unranking maps have done with visual elements.
Visual: If it is suggestive in a sexual way, shows excessive amounts of skin on the person, or has the context of the person being close to/if not already naked, it has grounds to be un-ranked until a warning/different background is in place.
Audio is a bit more lenient right now. If you want to argue that audio should be targeted too, please make some points about what would warrant an unrank. Please do this instead of arguing why nothing should be changed because audio is bad too.
Edit: And again, I support a use for the age feature that would "hide" maps from younger players, and a guideline/rule that makes mappers have to set a age group for the elements. It's a winwin.
