If the scams become widespread people will react accordingly. Real kidnappers ripping fingernails for ransom will find that they get hung up on and now have to resort to other strategies to get past the spam and get payment. People will realize how easy it is to make a deepfake and just not care about photos of them in compromising situations since they could now always claim plausible deniability. Gullible people will fall victim of course, but it doesn't take much even today to have someone hand over their life to you with some social engineering. There's probably millions of bots that were doing just that with some canned responses and getting a good enough return to continue hosting the bot farm at least even before chatgpt. I doubt the internet scammer needs much sophistication to get a decent return.
