Until this problem is fixed, feel free to use the old browser proxy:
http://aoproxy.extropia.co.ukI've added a snippet of code to eliminate the iframe from the page and removed the automatic redirect to the main site for modern browsers. You can see the effect in the page source:

Unfortunately the iframe output breaks the page with respect to header based redirects, so you'll still see the "redirect" page when you click on "new posts" and the like, but I have confirmed the iframe is not present in any content that is passed through the proxy code.
