What websites are like ipfaker.com?

Answer 1

IPfaker.com and other such sites are proxies that allow you to access sites that have been blocked by your network administrator.

For eg. many schools block sites such as MySpace, many offices block movie/music download sites. You can access such restricted sites using a proxy site. Proxy sites fetch the content from the blocked site and present it to you.
