Apps with user-generated content or services that end up being used primarily for pornographic content, Chatroulette-style experiences, objectification of real people (e.g. “hot-or-not” voting), making physical threats, or bullying do not belong on the App Store and may be removed without notice. If your app includes user-generated content from a web-based service, it may display incidental mature “NSFW” content, provided that the content is hidden by default and only displayed when the user turns it on via your website.
Creator Content
Apps which feature content from a specific community of users called “creators” are a great opportunity if properly moderated. These apps present a singular, unified experience for customers to interact with various kinds of creator content. They offer tools and programs to help this community of non-developer creators to author, share, and monetize user-generated experiences. These experiences must not change the core features and functionality of the native app—rather, they add content to those structured experiences. These experiences are not native “apps” coded by developers—they are content within the app itself and are treated as user-generated content by App Review. Such creator content may include video, articles, audio, and even casual games. The App Store supports apps offering such user-generated content so long as they follow all Guidelines, including Guideline 1.2 for moderating user-generated content and Guideline 3.1.1 for payments and in-app purchases. Creator apps should share the age rating of the highest age-rated creator content available in the app, and communicate to users which content requires additional purchases.
