Hey there, my ISP has blocked the site, I've heard that it is possible to bypass this block by using a proxy server. Please tell me more about what is a proxy server, and how to use it to bypass the block?

Basically, a proxy server is another computer which acts as an intermediary between client (e.g. Your computer) and the remote server, which client is accessing to. Using a proxy server, your computer sends requests to the proxy server instead of the desired destination, proxy server processes your request and returns what you were wanting.

The simplest solution is using a web-proxy server.
