Unblocking Websites like friendster.com etc.

More often, your access to some websites (such as Friendster.com) will be blocked by a "content filter" on your network. Content filters are popular in schools, businesses, and on some public access networks.

Content filters block access to sites which are deemed undesirable, because they contain content that people don't want you to see, or at least don't want you to see right then.

This type of block is designed to block where you are going to, not where you are coming from. The best way to get around this type of block is to use a anonymous proxy

Here are some anonymous proxy I search in the web that really working
