A number of websites are continually banned by the authorities, e.g. torrent sites by the government, Facebook by certain companies, and many others through university proxies. We here are strong supporters of freedom of choice, and show how to bypass such restrictions and access (most) blocked sites easily.
Quoting the website, Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis.
A number of volunteers and Tor users around the world run a distributed network of relays. When you need to access a site which is blocked in your region, you use Tor to route the communication through one of the relays, situated where the same site has not been blocked. Think of it as a massive network of proxies.
Download the Tor Browser Bundle off the website to get started. It contains the core Tor software, the Vidalia GUI, and a configured-for-Tor version of Firefox.
Extract the bundle and click on the Start Tor Browser.
Go to Settings -> Network if you access internet through a proxy.
Once you’re connected to the Tor network, Firefox opens up and you can (almost) any website anonymously. If it so happens that the website you wish to access is also blocked through the connected relay, simply click on Use a New Identity to try through another connection.
You can see a map of the Tor network and the bandwidth usage, apart from settings through the Vidalia Control Panel.
To use the relaying with another software go to Settings -> Advanced and note the local address through which to route the connections. Use it as the proxy in any software you want to use Tor with. (You might want to set Authentication to none). Try to use HTTPS connections instead of HTTP.
Contributing to the Network
Click on Setup Relaying in the Vidalia Control Panel, and select the type of relay you want to contribute. Enter the basic settings, letting automatic port forwarding checked. Set a bandwidth limit so that your connection is not totally hogged. Allow Tor connections through your firewall.
If you face any difficulty in this step, refer to the official guide.
We hope that this post relieved you a lot of frustration regrading the <mostly> unnecessary banning of certain websites
