The reason why there aren't any 1-star projects isn't because they don't exist, but because we didn't think anyone would want to see them. Cataloguing these was a ton of work (we sifted through hundreds of tests). Including the 1-star ones seemed like it would only shame companies who used them.
I appreciate that you might not want to name-and-shame. I wonder if you could just scrub the identifying info and post them, though?
Personally I think it'd still be tremendously valuable to show clear examples of what "bad" looks like in your ranking system. Not only does it help you show off more of the hard work you did, but it also helps all your readers get a more complete understanding of your framework.
Beyond that, it's generally helpful -- in learning anything complex -- to see examples of "what not to do, and why."
