I just came across the joints tag, and I'm not sure what to make of it. It seems like its intended use is for species with prominent articulated joints like robots and insects, but it's also used to tag marijuana joints. I'd propose a disambiguation, but I'm not sure if there's any point to tagging the anatomical feature in the first place. In the same way that basic anatomical features like nose and leg are invalid, it seems too ubiquitous to use as a valid tag.
