Although the majority of the sites are blocked on the basis of containing illegal contents or services, websites with contents related to for example politics and Kurdish insurgency are also blocked. While Turkish Internet users are very much interested in the political corruption in the highest echelons of politics, relevant websites do not exist. This scarcity could be seen as a result of the perception that they will be banned anyway. Instead, the news and ideas in these categories are usually disseminated in global social media platforms such as Twitter where they get more international visibility if they get banned. In recent years, blocking of Twitter, Facebook and YouTube in the country has frequently raised international concerns.
