To me, that sounds like they are going after underage hentai, which is a can of worms I don't even want to think about.<p>I ran into the fringe of this in the SD community in 2022. There is a 4chan model, which I shall not name, that I <i>vaguely suspect</i> contained (real life) underage pictures in the dataset. This model was merged into at least two other popular models awhile ago, hence I think it has "polluted" many other SD 1.5 models down the merging family tree.
Ironically this might be used as a training dataset to detect pedo content and kick out some asses.
Most idiots in these networks do it for power instead of trying to improve themselves in life, so they don't care a lot on data mangling to confuse the data detection algorithms, such as using checkered semi-transparent alpha layers or kinds of high-contrasted layers with polygonal shapes.
