Oh no, even now you cannot really use public available services to generate any "interesting" pic.

To create the one above I used my own pc, with a very old nvidia 1050 (it takes about 3 minutes per image like that one).

Not only are prompts "sanitized" but the model (the trained source of reference for the creation of the images) is usually trained on a safe image base, those that let you do nsfw themed images cannot really do younger looking people, the anime types stay away from loli content, loli models are kept separated from guro sources, etc…

This means that even on your own pc, if you use a pre-trained model set you cannot really do many things.

I'm starting to explore how to train my own but it's going to be very time consuming, especially since I don't have a good dataset of correctly tagged guro images.
