Don't you all hate it as well?
Just because your only interest is, well, boobs and your boss is either gay or catholic (or an unholy mixture of both) you have a crappy word- and ip-filter that keeps you away from the sites you'd need sooooo badly!
But there's a solution called "CGI-Proxies".
One example could be found here:
http://greenrabbit.org/
Just type in any URL into the form and you're good to go.
BTW, the owner of this page honestly sucks, since he stole the script from
http://whitefyre.com/poxy/
and completely removed all links to the origin site, so I decided to put his site up here in case he may have to pay for the bandwidth.
Enjoy
