据all facebook网站的报道，facebook对线上顶尖的应用程序开发商提出了更高的要求。

facebook的官方公告称应用开发商如果旗下的应用月活跃用户达到或者即将达到500万，就必须和facebook官方取得联系，会有一些额外的条款。

facebook新闻发言人称他们现在只是把门槛从日活跃用户500万提升到月活跃用户500万（指单个开发商旗下所有应用一个月的月活跃用户综合，意味着关联的开发者扩大了，那些不是很出名的开发者也就有可能被纳入这个体系内）。

Facebook has raised the bar for application developers – creating new rules for applications with more than 5 million active monthly users. Previously the additional requirements only kicked in for applications with more than 5 million active daily users.

The terms on the Facebook Developer Principles & Policies page have been updated with the following clause:

“If you exceed, or plan to exceed, any of the following thresholds please contact us as you may be subject to additional terms: (>5M MAU) or (>100M API calls per day) or (>50M impressions per day).”

A Facebook spokesperson told Inside Facebook the move was prompted by the need to maintain quality service on the Facebook Platform.

“We recently revised our threshold policy from 5 million daily active users to 5 million monthly active users,” the spokesperson said. “We want to work closely with our largest developers in order to maintain a high level of performance, speed and uptime for Facbook Platform. Sudden, unexpected large increases in API usage could negatively impact both developers and users.”

The additional requirements for large application developers are undisclosed but AllFacebook understand they are related to site performance. With the social networking site recently reaching 500 million users, maintaining stability of the platform as the user base grows is a key challenge for Facebook’s network engineers.
