I didn't realize that you needed the extension to view them. I had thought that all the extension did was lookup links on the current page and add a badge to them summarizing their overall NewsGuard score, and add a mouseover popup for the badges to see the full score, and provide a link to the full report.

Edit: actually, the links aren't working for me now, either, and I DO have the extension installed.

Edit: it looks like they are time limited links. I just went to Zero Hedge again, got a NewsGuard link, and the long hex string is different. That new link works for me regardless of whether or not I am on a browser with NewsGuard, presumably until it too times out. I don't see any way to make a permanent link to their report for a site.
