New online speech restrictions are taking effect Friday in Russia, making it more difficult for bloggers to remain anonymous and requiring social-networking sites like Facebook to retain user data for at least six months. Under a measure approved by Russia's parliament in April, the law also demands that the social media data be stored within the country's boundaries so it can be available for government inspection. Human Rights Watch called the development "another milestone in Russia's relentless crackdown on free expression," in a statement given to the BBC.
