So what if they do? You can't let other people dictate your emotions or they will take advantage of you any way possible. That feeling of shame and embarrassment comes from within, not from the scammer, and therefore you have power over it, not them. There's no sadistic pleasure to be had if the victim doesn't care. If the victim doesn't care, why should the scammer waste their time? But just in case they do, good thing there's that facebook feature that hides messages from obscure users. By the time someone ever finds the message, you can just say it was a deepfake.
