我收到警报：这违反了Facebook平台政策4.8，但看不到为什么？ [英] I'm getting alert: This violates Facebook Platform Policy 4.8 but can't see why?

问题描述

我不断收到有关该应用将用户重定向到Facebook平台的主要目的的警报。整个应用程序在社区内进行，甚至通过要求用户返回时间表来完成。有人能够阐明冲突吗？该应用程序是一项投票竞赛： http://bit.ly/UlsterWeddings

I'm getting constant alerts about the primary purpose of the app redirecting people off the Facebook platform. The entire app takes place within the community and even finishes by asking the user to return to the timeline. Would someone be able to shed light on the conflict. The app is a voting competition: http://bit.ly/UlsterWeddings

任何帮助将不胜感激。警报如下。

Any help would be greatly appreciated. The alert is below.

警报：您的应用似乎具有Canvas集成，可将人们重定向到Facebook。这违反了Facebook平台政策4.8：请勿构建主要目的是将用户重定向到Facebook的应用。为了让我们考虑您的上诉，您的应用将需要停止将用户从Facebook重定向出去。

THE ALERT: Your app appears to have a Canvas integration that redirects people away from Facebook. This violates Facebook Platform Policy 4.8: "Don’t build an app whose primary purpose is to redirect people off of Facebook." In order for us to consider your appeal, your app will need to stop redirecting users off of Facebook.

推荐答案

我已收到该警报以及在Facebook上的Facebook Developer Community组中正在讨论它的许多其他开发人员。

I've received this alert as well, as have many other developers who are discussing it in the Facebook Developer Community group on Facebook.

就术语而言，我们都在同一页上，画布是指在facebook.com上的iframe中使用Facebook chrome /显示的应用程序网页应用页面内容周围的导航元素。 Facebook将某些api方法限制为仅在画布页面上可用，并禁止未经批准的广告提供商（阅读：Adsense）在画布页面上。

Just so we are all on the same page with respect to terminology, "canvas" refers to application web pages displayed in an iframe on facebook.com with the Facebook chrome/navigation elements surrounding the app's page content. Facebook restricts some api methods to only being available on canvas pages, and prohibits unapproved advertising providers (read: Adsense) on canvas pages.

根据我的收集，今天Facebook部署了一个新的自动策略执行脚本，这就是为什么许多应用程序现在才看到此警报的原因。以典型的Facebook方式，没有提供有用的可操作信息。这项政策本身并没有改变，但建议我观看以下视频： https：/ /www.youtube.com/watch?v=tYcxyh5HQSI#t=94

From what I've gathered, today Facebook deployed a new automated policy enforcement script which is why many apps are seeing this alert just now. In typical Facebook fashion, no useful actionable information is provided. The policy itself has not changed, but I was advised to review this video: https://www.youtube.com/watch?v=tYcxyh5HQSI#t=94

视频中的最后一个示例是用户单击以下链接他们的信息流中的一条信息。在示例中，单击链接会将用户带到画布外页面。一位Facebook政策雇员告诉我，这是我的应用违反政策的行为。

The final example in the video is of a user clicking on a link from a post in their stream. In the example, clicking the link takes the user to an off-canvas page. I was told by a Facebook policy employee that this is specifically what my app is doing in violation of the policy.

我的结论是，Facebook加大了执法力度，大大加强了对政策的解释：如果您的应用允许用户在画布页面上发布帖子，则帖子中的所有链接都只能进入画布页面。这就是我的解释，似乎与您在视频中看到的内容以及Facebook政策执行人员告诉我的内容一致。

My conclusion from this is that Facebook have ratcheted up enforcement and significantly tightened up their interpretation of the policy: if your app allows the user to make a post while they are on a canvas page, any links in the post must go only to canvas pages. That is my interpretation which seems to follow from what you see in the video, and from what a Facebook policy enforcement employee told me.

与以往的解释大相径庭的政策。我猜想成千上万的Facebook应用违反了这项政策，因为它现在正在被解释。我首先将放弃画布，回到具有Facebook集成功能的简单网站。

This is a huge departure from past interpretations of the policy. I am guessing that thousands (tens of thousands?) of Facebook apps violate this policy as it is now being interpreted. I for one shall be abandoning canvas and going back to a simple website with Facebook integration.
