well, im assuming your school's computer system is probably very tough :T Google images, myspace, and all sorts of sites other sites that arent even porn related, are blocked from my school as well (even when the site is school related every now and then). I just use proxies to bypass, dont look up proxies if you're in school, cuz of course itll be blocked, just look them up at home then email it to yourself or write it down so you can use it at school [that is if you're that desperate to get on those sites]
