苹果app上线审核被拒 Guideline 1.2 - Safety - User Generated Content

We found in our review that your app includes user-generated content but does not have all the required precautions. Apps with user-generated content must take specific steps to moderate content and prevent abusive behavior.

Next Steps

To resolve this issue, please revise your app to implement the following precautions:

• A mechanism for users to flag objectionable(会引起反感的) content
• A mechanism for users to block abusive(不法的) users
• The developer must act on objectionable content reports within 24 hours by removing the content and ejecting the user who provided the offending content
  （开发商必须在24小时内对不良内容报告采取行动，删除内容并驱逐提供违规内容的用户）

我们在审查中发现，你们的应用包含用户生成的内容，但没有采取所有必要的预防措施。包含用户生成内容的应用程序必须采取具体措施来节制内容，防止滥用行为。
下一个步骤

要解决此问题，请修改您的应用程序以实现以下预防措施:

-用户标记不良内容的机制
-用户阻止滥用用户的机制
-开发商必须在24小时内对不良内容报告采取行动，删除内容并驱逐提供违规内容的用户
