This is not going to work. Artists need to contact the makers of those models themselves. Nobody creating a model in order to sell it would care what an aggregator site says.
I agree, they do need to contact the creators of the models that are trained on their work. As for people caring what an "aggregator site" says, I think that's selling Danbooru a bit short. This site is one of the best places for people to lookup information about an artist they like. I'd argue it's moved beyond it's roots as merely an imageboard and has become, or at least could become, more of archive of art with a database of high quality metadata.
If the data doesn't exist or isn't easily available then I agree nobody will care, but if it does then I think it can be of use genuine use to someone out there. That someone could be a good-faith AI model developer, a site like Spawning.ai, or potentially even artists themselves fighting against companies that profit off of their work such as NovelAI.
