Since 2004, the web has evolved to be read-write, marking the beginning of Web 2.0 era. The rise of social media allows users to share user-generated content and engage in online discussions. While enjoying a more interactive online experience, users are sacrificing their privacy to service providers such as Facebook. Because service providers own and manage the data collected from their users. They frequently track and save the data, and use it for targeted ads. Moreover, Web 2.0 leaves content creators limited control over their data, because service providers have the authority to block any account and manipulate the exposure of posts.
