we built https://haveibeentrained.com that does the same CLIP retrieval process, and arranged for artists to be able to opt out of future trainings with Stability and LAION.

If this is just CLIP retrieval, that raises some ethical problems with the pretense of this site. It could make artists look silly for depending on an overstated claim of provenance, or worse still have artists pursue AI artists because an image looked kind of like their own artwork, with nothing more behind it.
