Yo!
So, a quick preamble...
Amongst the art that caters to less-anthropomorphic designs, anatomically_correct is used broadly.
It was introduced to tag characters of a given species with anatomical features suited to their real-world counterpart: canines with canid breasts; equines with equine penises.This tag solved a few problems.
Mostly, it disambiguated the 'feral' tag, allowing users who browse that tag to filter for designs that are not extraordinary; bodies that are more coherent.
However, years on, it's obvious that the tag has lost that coherency.The subtext is that anatomically_correct is used euphemistically; a way of pointing towards non-anthropmorphic designs which skirts around controversy, in the same way that 'forced' is used regarding rape scenarios and 'young' is used regarding content depicting underage characters.
However, in being used euphemistically, it is used incorrectly.
Taking the tag at face value, you would expect anatomy that is correct... but the tag is littered with artwork which *simply does not* have correct anatomy.
Why? Because it is being used to mean 'non-anthropomorphic' instead.
The standards for tagging an artpiece with 'anatomically_correct' should be raised, so that artwork using it has correct anatomy.
Why is this an issue?
Well, taking a peek through the tag's first page, we see artwork such as https://e621.net/posts/4295714 and https://e621.net/posts/4281655; valid posts with a place on the site, but would not be described as having 'correct anatomy'. The reason why those arts have been tagged as 'anatomically_correct' is because the tag is being used in the euphemistic manner described above.
On the other hand, you have artpieces such as https://e621.net/posts/4296301 and https://e621.net/posts/4289394, where the creator's focus on anatomical accuracy is an obvious and intended part of the art-piece. My suggestion is that the standards for applying this tag should be that anatomical accuracy is a stylistic choice that has been obviously intended by the artist.
A tag which is applied too broadly loses meaning.
As a user, it's frustrating that a tag which has so much potential to highlight a particular artistic feature isn't being used to its advantage.
Would love to get other's thoughts.
