I recently found a list of proxy websites which is updated regularly and fresh proxies are regularly added on this list of proxy sites. These proxy websites can be used to unblock MySpace, Orkut, Facebook, Meebo and other communities from any kind of internet network. There are different purposes of proxy servers and proxy websites. Your internet network cannot filter these proxy websites as these proxy servers are completely new and if one proxy is detected and blocked by your network filter, you can use another proxy server which is working. A proxy server is basically a server which provides their clients to use this server to request the resources from another server.
If your school or college internet network blocks some of the community like Facebook, MySpace or Orkut, then you can use these proxy sites to access those websites from your internet network. If you are using a proxy website, then you are not directly surfing from your IP address or server and therefore your computer is conneected to the internet through another proxy server. There are some people, mostly internet marketers, who use proxy servers as bypass proxy. Craigslist and Gumtree are two major classified Ads which are used by many marketers and business people to advertise their products. If your IP is blocked and you cannot access to these websites, then you can use proxy websites to access websites.
There are some proxies which are working for unblocking MySpace, Orkut, Facebook, Meebo, Craigslist and Gumtree:
Proxy server can also be used by using proxy software but you need to install proxy software which nobody wants to do. If you are using proxy websites, then you can directly use the address bar in the proxy websites to surf the internet directly. Some people use proxy servers as they want to surf the internet anonymously and do not want to show their IP address for security reasons. There are different proxy servers like anonymizing proxy servers, hostile proxy servers, forced proxy servers, open proxy servers, reverse proxy servers and many more. As a proxy user, you do not need to know about all these proxy servers as you can surf all the websites using the new proxy sites in the list.
