Sora might have a 'pervert' problem on its hands (via) Katie Notopoulos turned on the Sora 2 option where anyone can make a video featuring her cameo, and then:

I found a stranger had made a video where I appeared pregnant. A quick look at the user's profile, and I saw that this person's entire Sora profile was made up of this genre — video after video of women with big, pregnant bellies. I recognized immediately what this was: fetish content.

This feels like an intractable problem to me: given the enormous array of fetishes it's hard to imagine a classifier that could protect people from having their likeness used in this way.

Best to be aware of this risk before turning on any settings that allow strangers to reuse your image... and that's only an option for tools that implement a robust opt-in mechanism like Sora does.
