That's a funny mistake!

I commend your willingness to push back against AI porn, as there is enough high quality porn made by actual people that we don't need to peddle in slop. But I would recommend doing a reverse image search or two before you make such a declarative statement again. If the picture predates the rise of generative AI, then it's not generated by AI.

Also, be aware that there are some older pictures that have been AI upscaled that can give a false impression.
