Issues relating to privacy over social media websites have been hotly debated for some time. It is widely believed that the privacy policies of these websites are not completely transparent. This chapter considers the latest trends on two popular social media websites and one mobile application, viz., Facebook, Twitter, and Snapchat. For our purposes, these three together will be considered as social media platforms. Privacy policies continue to be a contentious issue at the present time with social media platforms not always fulfilling the requirements of data protection principles, although we see a desire to make such policies a lot more transparent than they used to be. The chapter identifies the tools that help users to control dissemination of personal information over these platforms. It concludes by noting that existing controls are marred by complications, since users are still not sure of what to expect from existing privacy settings.
