There was a small number of crazy anime nerds rotating accounts tokenmaxxing Grok image generation to generate anime and cosplayer porn shorts with egregiously low yields and no intention of even publishing the results let alone monetizing, something like <1 result per daily quota across few accounts. Grok was briefly focused on adult usage, and they took advantage of that, until it was too much for even xAI. It seems British online advocacy groups tend to use "CSAM" as circumlocution for "anime", perhaps inspired by the fact that both imagined and real figures seen in anime related content always look to be below legal ages to some to the point that said some thinks it can be banned as willfully depicting underaged entities, so maybe this is a push coming from that direction.
