Also , in a number of countries , religious controls are the prime motivator behind internet censorship , limiting the exposure and spread of contradictory ideas . Deliberately formed notions of compromised national security and threats to stable social development are also invoked by governments in order to impose internet censorship .
Other than this internet censorship is used to prevent theft of intellectual property such as limitations and reforms imposed against illegal download of copyright content or music . A few governments also use censorship in order to oppress minorities , under the umbrella of cultural restrictions . For instance , the unavailability of certain government websites in different languages maybe viewed as the suppression of certain ethnic minorities .

China , Iran , Russia and India are some of the worst internet censorship states engaging in heavy censorship strategies .
