They could be, and you can’t know, but I do think it’s pretty unlikely for my immediate family - we’ve already survived my sister‘s vengeful long term ex who told pretty astute lies to try to divide us and we’re all the same kind of autistic, so we have a mutual understanding based on hundreds of conversations most people would hate that we’re all very kantian in our own ways about ethics (which, to be fair, would in my case definitely preclude me from volunteering to be a soldier in most situations, but that kind of breaks the hypothetical).

If they didn’t know that AI generated images existed and didn’t know that I was in a situation where blackmail was a concern, it might be different, but in this situation they’d probably need a lot of evidence of different types to start to wonder if I was a monster.

They also wouldn’t think I was a monster for masturbating, taking nudes, or shitting, which helps.

Besides, if they were somehow turned against me, it would be no less devastating by knowing about the possibility beforehand, so I don’t really see the point in trying to figure out exactly what it would take.
