All countries "ban specific parts of the internet" insofar as they have laws that make certain business models illegal and, those businesses being illegal, websites for them don't exist in the first place. For instance, websites to sell your organs are "illegal" in America because buying organs from people isn't a legal business practice in America. That kind of business isn't allowed, therefore that kind of website doesn't exist. So you don't ban social media websites; you ban social media business practices.
