Since the TOS prohibit any and all explicit NSFW content on the platform it would be best to update the SDK to check for the more commonly used NSFW packages, assets, and meshes etc and block that avitar from being uploaded if any are detected.

Most users do not have the skills necessary to implement NSFW features and rely on 3rd party packages and assets such as DPS / SPS. I understand that it will never be perfect given the customizability of avitars but building a list of common known NSFW hashes to check against seems like low hanging fruit for keeping NSFW content off the platform.
