Try this: Take a photo and upload it to Facebook, then after a day or so, note what the URL link to the picture is and then delete it.

试试这个：拍一张照片，上传到 Facebook，然后过一两天，注意照片的 URL 链接是什么，然后删除它。

This week's comic doodle reportedly only shows in the US, unless you call up a special URL.

据报道，本周的漫画涂鸦只在美国展示，除非你访问一个特定的统一资源定位地址。

In the case of Facebook, the company says data may hang around until the URL in question is reused, which is usually "after a short period of time", though obviously that time can vary considerably.

以 Facebook 为例，该公司表示，在该链接被重用之前，数据可能会一直存在，通常是“在很短的时间之后”，不过很明显，这段时间的长度可能很不确定。
