As per Community Rule 5, all visual content submitted or uploaded to osu! must be considered as appropriate for an all-ages game.
In the interest of keeping things as clean as possible, Community Rule 5 applies to anything that could be reasonably considered "questionable".
All pictures should be judged as they are, without factoring in any other cases before them. Decide based on what you see.
Please also understand that we are a global, multicultural community with widely varying thoughts, opinions, and values on the topic of what is and isn't allowed.
When in doubt, aim to accommodate the collective values shared by the largest portion of the osu! community in general.
Images or visual elements containing any of the following are not allowed:
Images or visual elements containing examples of the following may be considered acceptable:
Images that are used anywhere on the site outside of a beatmap (avatars, profile covers, userpages, etc) are not subject to the voting procedure explained below and may be removed at any time at the discretion of the Global Moderation Team.
If you are unsure about an image that is going to be included in a beatmap in any way, please submit a request via the Beatmap Nominator Report Submission page. The image will be raised to a vote that must pass by a considerable majority, or will be automatically denied.
The result of any vote is final, unless the image is significantly altered in an attempt to resolve any potentially problematic elements raised during discussion.
At all times, the osu!team reserves the right to unilaterally declare any piece of content either valid or invalid at their discretion, regardless of any previous voting held on the matter.
