This is already an issue in email marketing. The gold standard of course is emailing people who are double opted in and only telling the truth, and if AI is used to help create that sort of email I don't really have a problem. There is basically a spectrum where the farther away you get from that the progressively more illegal/immoral your campaigns become. By the time you are shooting lies into thousands of inboxes for commercial purposes... you are the bad guy.
