Internet censorship circumvention - Definition from the Hotspot Shield Glossary
When the internet is censored by governments, there are always individuals or organizations who disagree with this censorship and feel it is a breach of their freedom and privacy.
Due to this conflict of interests, internet users have developed means of circumventing internet censorship and getting around the blocks a government may put in place. There are various methods that can be employed to bypass censorship such as using a VPN or proxies to hide your true location and IP address, accessing cached pages, using mirror websites, or even web to email services. It should be noted that circumvention and anonymity are two different things completely - Circumvention is working around a block, whereas anonymity deals exclusively with hiding your identity.
