Trained on images that were mostly SFW but had one key element making them NSFW. Weird how that works.

It doesn't really do anything that SD wasn't already doing with our prompts to make people naked in weird places, just now it is doing it with less prompting.

It'll occasionally make some very detailed holes that aren't sexual in nature, but are unsettling to look at. Makes nice looking genitals though, so it makes up for it.
