Furl.net RSS feed is showing urls as redirects, instead of a direct link to your site. So that should now be removed.
This is a new one to add:

Mister Wong doesn't use auto-discovery for their feeds. So you wouldn't necessarily know that they have them. I only recently found this, when I searched across the page manually.
