Intro & Context
Some people have made forum threads like this one from last month arguing that backgrounds should be more strictly moderated. In addition, some users like sst3w have argued in YouTube videos that such backgrounds harm the community in various ways.
However, a recurring pattern is that none of these discussions mention the relevant rules. I'll be laying them out and analyzing them in this post.
Other than the aforementioned posts and reasons, I'm not bringing this up in relation to any particular event(s).
The rules on beatmap backgrounds, as with all images or other visual content in the game, can be found in the Visual Content Considerations. It states that:
- An image may not contain "significant sexual innuendo", "sexual posturing or solicitation", "erotic content[,] or graphic displays of sexuality".
- Images may not contain "sexual content involving or targeted at minors" either.
- Anything deemed "questionable" may be deemed unacceptable based on the above rules.
- However, images containing "swimsuits of reasonable design" are usually acceptable.
- Should it be unclear whether an image is violating the above rules, it is sent to Content Review and must pass by at least 70% of either moderators or moderators + BNs.
Analysis
The rule that is generally used against images with excessively revealing swimsuit designs is that against "erotic content or graphic displays of sexuality". This would be an extremely high standard, if not for the principle about applying to "questionable" content as well.
This principle is derived from community rule #5: "We are an all-ages community". The practical interpretation of this rule by moderators is that content generally accepted as suitable for users over the age of 13 (such as swearing) is acceptable, but content only suitable for people over 16 (or otherwise disturbing/content-warning-worthy content) is generally not allowed.
While the rules state that "swimsuits of reasonable design" are allowed, they do not say swimsuits of unreasonable design are disallowed. The "reasonable design" rule is there to prevent someone reporting any image with a swimsuit and (for beatmap backgrounds) allowing them to close the report as falling under "the most obvious cases".
The practical result is that BNs, NATs, and GMTs doing Content Review for such backgrounds must decide whether the swimsuit design is appropriate for the average 13/14-year-old to view. Since a swimsuit has to be very revealing to be deemed likely inappropriate for a 13-year-old, most such backgrounds pass.
Backgrounds that pass are permanently usable due to the rule that "The result of any vote is final".
The rule regarding "sexual content involving or targeted at minors" means that if a background contains a character that looks childlike (such as lolicon or shotacon), the bar to deem that background unacceptable is reduced to the significantly stricter standard of merely "sexual content". (Note that some people are stricter and interpret "minors" to mean anyone that could reasonably be under 18.)
Notice the implication that in other cases, "sexual content" is allowed to a degree. Just like with rating boards in real life, milder sexual content is deemed acceptable for an audience over 13.
My Opinion
I find the current system acceptable for general visual content, but agree that it would be helpful to make the rules stricter for swimsuit designs in beatmap backgrounds.
