The Red Rule, as per my understanding, is that you can't force a character into something where the player isn't willing.
This seems like it would contradict The Red Rule, but a lot of people are willing to play NC games even when their characters absolutely wouldn't be.
I played a game once where my character was hypnotized and seduced while under a trance, and we put it in NC. I think Unnatural Mental Influence would certainly qualify there.
UMI is apparently now called Psyche, and it looks like Monk-Seducing Demon Dance and most other Charms aren't actually Psyche, so it seems moot.
