Facebook隐私保护再遭质疑：为什么隐藏的内容还会显示？
去年11月Facebook推出了雄心勃勃的Beacon广告计划，结果因涉及泄漏用户隐私而遭到强烈反对（这篇文章有一些对这个事件的介绍），最终不了了之。此后Facebook出台了很多保护用户的措施，比如下面就是极关键的一个：
这就是那个在beacon当中惹麻烦的mini-feed，相当于“个人新闻板报”，用户的在facebook上的行为会被记录在这里，朋友订阅了这个feed，就可以了解你的行动。为了保护用户隐私，facebook增加了“隐藏（hide story）”这个功能，具体做法是点击右上角的关闭按钮，然后会弹出提示框，再选择隐藏，这条消息就不会出现在被订阅的feed当中了，也就是说朋友就看不到了。
可糟糕的是，也许这个消息只是自己看不到，而朋友们都可以看到！Techcrunch收集了一些例证，比如这里和这里。Facebook还没有解释此事，我将继续予以关注。
Facebook News Feed Reports on You Behind Your Back
