Facebook’s recommendation algorithm is promoting fully nude, often AI-generated hentai images into people’s news feeds, the latest of many signs that Meta has stopped uniformly enforcing its own rules and does not even remotely have a handle on its AI-generated spam problem.
Like much of the spam we’ve seen recommended on Facebook, many of these images have tens of thousands of likes and hundreds of comments. While some of the hentai has telltale signs of being AI-generated (bizarre hands on the waifus, watermarks for an AI porn image generator for example), many of the images do not look AI-generated and are likely stolen from various hentai artists on the internet. Some of the images have watermarks of Patreon artists who sell access to their hentai, suggesting that many of the images were drawn by human artists but have been stolen from them to spam Facebook.
Ironically, discerning AI-generated hentai from human-made hentai can be quite difficult because one of the most popular uses of AI image generators is to make hentai and, so the technology has become quite sophisticated.
I originally found this content because someone posted a hentai photo that they blurred in an AI group I follow. “Holy cow. Facebook's crazy algorithm does it again, and now my feed is showing me tons of clearly AI made naked cartoony girls,” they wrote. “I blacked out the bits here just to protect myself, but yea, they were 100% right there. Also saw a few Disney princesses nude which is gross if you think about it for a second.” From there, I searched the caption a spammer posted alongside the nude waifu, which was “Hello, a loving greeting.” From there I found dozens of pages of viral nude waifus, including, for example, nude images of Elsa and Anna from Disney’s Frozen series and images of Misty from Pokémon.
