Blame all the angry Karen's of the world... Just look what's happening with steam and the credit card companies. If you want anything remotely adult these days you get shut down.
civitai and loads of others just blocked uk user access by threat of UK law to try an limit the amount of AI gens because a small number gen celebs or worse
I think that if the celeb genning craze not taken off Dalle would still be the number 1 stop shop for lewd gens. Soon as legal terms and financial losses come into play it gets nerfed
All it does is drive folks underground where they create even more niche communities (only gotta look at /b to see the depravity on display)
I've used sd and pony for Elsa and anna gens for months now but nothing beats Dalle for it's pure ease of use and speed
