The AI fake stuff is, on one hand, private and harmless and morally pretty similar to personal fantasizing. And fantasizing about platonic friends/acquaintances is more common than most girls realize. Aaaand at the same time, it’s understandably very disturbing to find out someone is doing that with your likeness. I get why she’d be so creeped out. (Which does call the harmlessness point into question; if there is a chance the person finds out and is disturbed, it’s not so harmless)
But to bring it up publicly now is probably for more petty reasons.
As a side note, man the brief glory days of free AI nsfw image/video edits were so good…
