In accessing restricted websites, what you need is a tunnel proxy that will serve as a buffer between you and the website you are trying to access. Tunnel proxy is usually included in proxy server list. With tunnel proxies, you are given the chance to access any website you want even if they are restricted and blocked. Users will try to access blocked websites directly but what you can do is use a tunnel proxy and connect there. Use it as a port to the website and the proxy will be the one to connect you to the Internet resource you are accessing.
