Do you plan to implement perceptual image hashing (https://en.wikipedia.org/wiki/Perceptual_hashing)? It would be possible to ban bad images by hash then (and also it's useful for finding alternative versions of images - of better quality for example).

    it doesn't talk about techniques

    It's all scattered among different articles - external links in "Perceptual hashing" page, algorithms section in https://en.wikipedia.org/wiki/Reverse_image_search , some vague description in https://en.wikipedia.org/wiki/PhotoDNA (this one is big: "As of 2022, PhotoDNA was widely used by online service providers for their content moderation efforts including Google's Gmail, Twitter, Facebook, Adobe Systems, Reddit, Discord.")
