"For example, the 2008 version of Facebook’s guide explains in detail the different types of information it collects on its users, but it does not address the legal requirements necessary to obtain this data. In contrast, the 2009 version groups this information into three categories (basic subscriber information, limited content, and remaining content) and describes, under the Electronic Communications Privacy Act (ECPA), the different legal processes required to obtain the various data. However, the 2010 version merely says that the company “will provide records as required by law.” Facebook doesn’t explain why it changed its language from year to year. While the 2010 guide’s language may allow the company to be flexible in responding to requests under a complicated and outdated statute, it does so through a loss of transparency into how it handles these requests."?
