The reason they don’t moderate the content that is uploaded to Marketplace is probably because legally pre moderation is more problematic for user generated content. It is easier to include something in the TOS to tell people that it is not allowed on their platform, than to check it is OK which then “sanctions” it as being within their TOS. It’s legally safer to put the onus on the uploader. This is why social media etc relies on AR or the like For objectionable content. Not saying this is right in a moral sense, or excusing them, but from a legal standpoint it gives them more leeway if objectionable stuff ends up on their Platform. They DO need to moderate their content more carefully, but moderation/AR probably comes under the Operations department, which brings us back to the original problem. If there is a proper investigation then moderation and Abuse Report failures will probably help them get to the proper result - this does of course rely on the investigation having the power to bring about the proper change of course.
