Did they scrape public facebook posts? Snapchat? Vkontakte? Buy private images from onedrive/dropbox? If I put as the second word a female name, it almost always triggers nsfw filter. So I assume images in the training set are quite private.

[edit] Looking at these images feels uneasy, like I am looking at someones private photos. There is not enough "guidance" in a prompt like "IMG00012.JPG forbid" to account for these images, so it must all come from the training data.
I do not believe FLUX 1.1 pro has radically different training set than these previous open models, even if it is more prone to such generation.
It feels really off, so, again, is there any info on training data used for these models?
