Homestarunner?

It's high time that I add a link to homestarrunner.com over there on the left. No, your other left. Right. So I edited the template to include the icon, published it, and went to check out my handywork. But when I clicked the link, the Raythoen Proxy server threw up all over my browser. It was then that I noticed that I had typed "www.homestarunner.com" as the link-to site. When I added the missing R it worked fine. But now I'm wondering, what is at www.homestarunner.com that warrants the blockage of the site? Anyone? Anyone?
