Such a vanishingly small percentage of the images its not even worth calculating. Of course search engines also contain these links, LAION-5B only contains links not images as well....
protect the kids!!! or something. Can we do a scandal about how many 'extremist' images are in the data-set next too? anti-vaxer, climate denier, nazi, religious extremist propaganda, scientific misinformation. Maybe we're all safer off using corporate models with closed data sets so no one gets any of the wrong ideas.
