OP is editorializing the headline ("based on real people") to try to push some agenda here. The fact that 404 Media already has vendetta against sites like CivitAI is bad enough. No, a majority of the models are not porn, not based off of celebrities, and no animals were harmed in the making of this film. Sure, you can point to certain examples of celebrities type models, but most of them are just for concepts not a specific person, and celebrities like to put their pictures out there for anybody to train against. And I do mean anybody can train against these. The hardware requirements are not hard, and besides the Patreon-fueled efforts of certain contributers, it's just Joe Average people submitting their own LoRAs for concept training.
Let me ask you a simple question: Do you like the current situation with the exploitation of women coming from the real porn industry? Or would you prefer an outlet where there are no men or women (or children) exploited at all?
