Most web filtering companies use an internet-wide crawling robot that assesses the likelihood that a content is a certain type (i.e. "This content is 70% chance of porn, 40% chance of sports, and 30% chance of news" could be the outcome for one web page). The resultant database is then corrected by manual labor based on complaints or known flaws in the content-matching algorithms.

These are web sites that allow a user to access a site through them. They generally use PHP or CGI to implement the proxy functionality. These types of proxies are frequently used to gain access to web sites blocked by corporate or school proxies

www.netanonymous.info is an anonymous website unblocker & online privacy tool. Using our site you can access all the websites your network admin and/or country don’t want you to be looking at. Did you know Web sites often track, log, and analyze your IP address, geographical information, web browser, and other personal information? we make your browsing experience totally anonymous by hiding such information from the sites you visit. This website is completely free, but, it would be great if you could do one of the following, send a link to your friends, bookmark us, subscribe to our weekly proxy update or anything else that'll get more people using us!

Proxies have the ability to hide users IP addresses, meaning that what they do online is harder to track. This is excellent if your school or office has tracking software- they will no longer see that the two hours you were supposed to be working on a project in was used to surf your favourite social networking website or play an arcade game (or twenty). Now, even with Facebook, Myspace, Bebo and Orkut being blocked by thousands of administrative areas across the world, proxies can be used to visit them; and since employers will not know this, it is all the better for you. Our network is just one of the thousands of proxies available on the Internet, and it aims to bring you a fast, risk free and secure way to access the websites that you want to visit.
