Source? This would be pretty big news to the whole erotic roleplay community if true. Even just plain discussion, with no roleplay or fictional element whatsoever, of certain topics (obviously mature but otherwise wholesome ones, nothing abusive involved!) that's not strictly phrased to be extremely clinical and dehumanizing is straight-out rejected.

I'm not sure this is true... we heavily use Gemini for text and image generation in constrained life simulation games and even then we've seen a pretty consistent ~10-15% rejection rate, typically on innocuous stuff like characters flirting, dying, doing science (images of mixing chemicals are particularly notorious!), touching grass (presumably because of the "touching" keyword...?), etc. For the more adult stuff we technically support (violence, closed-door hookups, etc) the rejection rate may as well be 100%.

Would be very happy to see a source proving otherwise though; this has been a struggle to solve!
