Creating a deepfake marketplace trading in celebrity and private-person identities is ... quite the choice to make, legally (and ethically) speaking.
The dot in “CivitAI" is between “AI” and “com” if you are referring to the domain name, or just “there isn't one” if you are referring to the name.
Civitai is just a popular place to host stable diffusion models / LORAs / textual inversions, not some kind of fake nudes marketplace. It's the huggingface of stable diffusion.
The highlighted bounty feature is technically accurately, but misleadingly, described. Yes, people can and do post requests for models of real celebs there, but they also post requests for fictional character models, for concept models not tied to particular real or fictional characters, for technical assistance with model training, for people to generate showcase images for existing models.
[edit] The fact is we've had this kind of content for a long time, and we've developed techniques for identifying and removing it. There's great nudity detecting ML models. I suspect the choice was made in part ideologically, and in part to drive sensationalist coverage, and it looks like it's working.
No, they screen, remove, and ban people for policy violations. (And that has improved over time, at least, the violations that have slipped through have dropped over time.)
What isn't a policy violation is separate things which could be combined together or with other things to make something that would be a policy violations.
I dunno about early access.
Huggingface also has porn-focussed trained stable-diffusion models. [0] They also have celebrity-trained models. [1]
