Hiya for anyone that want's to bypass anoyying filters in school or college i recommend using a program called UltraSurf it's a small application that works in a similar manner to a proxy and reroutes your network traffic
It means you can acess any site you want securely and anonymously and also means you can access sites such as youtube and still display flash video, javascript etc + it never gets blocked
Just rename the attached file to .exe then click 'directly use ultrasurf'
hope this helps!
