Newly available documents shed light on such questions. Digital rights advocates at the Electronic Frontier Foundation have been suing federal agencies for months under the Freedom of Information Act with help from the Samuelson Clinic at UC Berkeley’s School of Law. The goal was to force open policies that explain when social networking sites can be used for government surveillance, data collection and investigations.

Results made public so far by EFF are available below for more than a dozen sites in a chart built by the Center for Investigative Reporting. Old and new policies alike are posted next to the document year, so you can compare possible changes over time. EFF argues that the variety among them shows how “social networking sites have struggled to develop consistent, straightforward policies.”
