One of the websites I read on a daily basis is Boing Boing. Some over-zealous webfiltering software classifies Boing Boing in such a way that it is blocked. To help rectify this situation, I've installed the Distributed Boing Boing proxy on this website. The URL for the proxy is http://willwyatt.com/dbb.php.
Freedom of information is important to me. I don't think organizations or whole countries should deny individuals the right to free information. Plus, Boing Boing isn't really a website that deserves to get blocked.
I'll leave the proxy up as long as it doesn't take too much bandwidth.
(If I'm serious about helping internet information, someday I'll bite the bullet and install the Tor network at Dreamhost or at home.)
