Maybe a silly question, but do you know what they use for AI art?
The most likely case would probably be Stable Diffusion, since it supports hardcore NSFW images and most other AI gens don't. If its Stable Diffusion (Automatic1111 is widely used), the art is controlled primarily by the text prompt which describes the scene/girl, and the model (can find on civitai.com) which is basically the database of images the program uses to make pictures. I don't know the specifics in this case.
By the way, I'm guessing this is a trend but the anti-AI art posts are starting to look an awful lot like criticisms of NTR or MTL, in that there are die-hard haters who want it all banned, regardless of the circumstances or reason. NTR is a matter of taste, MTL can be good and bad, and even when its bad as long as it doesn't break anything its still better then nothing at all, and as for AI art gens, they are tools. They have some SEVERE limitations, (more then non-users realize), but if used well, like any good tool they can be used to carefully enhance a work or create good ones, or they can be used sloppily to make bottom basement garbage. Don't confuse the use of the tool for the tool itself.
