Since coming to lemmy I will browse all vs local and top by day. There is a solid amount of AI generated porn that has many votes in a 24 hour period.
To me the whole vibe is plastic tits and "smooth" skin. It looks off even when done well and all the faces look the same. Is anything it's more a technical feat than what helps me beat my meat. Also it's nearly all white women or pale Asians.
Faces all looking the same is possibly because people are hesitant to post their AI images of IRL celebs etc. Stable diffusion is really good at creating that sort of thing
