The tag as it stands on the meta category describes a technical fault, best seen in post #3952427. Keyword technical, as it isn't a pitfall in the artist's ability itself like bad_anatomy but one related to an outside process. Say post #4185033 the image has visible scan_dust due to the scanner forgetting to clean the surface yet we wouldn't tag it dust as it isn't a feature of the illustration per se.
With aliasing I would concede there is plenty of mistagging, I wouldn't say post #4343427 is aliased by any means as the staircase effect of the lines is inherent to the style and medium the artist drew it in while aliasing is a distortion artifact.

Why not? It's the name of the practice, unless we want to make a disambiguation between pixel art aliasing and aliasing in higher res art.
We could use the informal name of the effect to tag said pictures if people are willing, it is called jaggies. The bottom line is that it's unproductive tagging post #4343427 and post #3952427 the same tag so I'd rather keep it a fault tag as it's closest to the original definition of "aliasing is an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled.". Pixel art can be anti aliased or any picture for that matter but applying a form of subpixel rendering manually to the very drawing also strays a little from the spatial anti-aliasing definition: "spatial anti-aliasing is a technique for minimizing the distortion artifacts known as aliasing when representing a high-resolution image at a lower resolution".
Although it as well depends on how useful is to point out the jaggies in the oekaki or pixelart.
