Bill Vicious & witchking00 comics shouldn't be listed as Doujinshis imo, they should be branded as "Western" as they exhibit very few if any of the qualities that define doujinshis

From the Tag definition:
Western:
"All pornographic art of western origin whether they are loose images, CG sets, or comics.
For images/works of any origin."
It honestly doesn't even matter what their work entails, the fact that they are obviously western creators already triggers that.
