One of the unwritten laws in most countries in recent times is the right or rather the freedom to use the internet as, where, when and what we see fit. But it should also be known that this basic facility is not that free in many countries around the world.
Internet censorship is actually a reality in most countries where in other it is only a matter which our parents concern themselves and not our government.
Many countries such as South Africa, China, Greece, Indonesia, Austria, Russia, etc have put their foot down into categories like pornography, political media, social media as well as torrents.
