I'm not a fan of AI specifically because of this sort of thing. If humans were better and not aholes, it would be fine. But humans *aren't* better and they *are* aholes, so here we are.
Remember when the internet was new to us and we were all like, "Oh, how cool! Here's this way to communicate with people all over the world, imparting information, getting information....what a great idea!" And it took like two seconds for aholes to use it for nefarious purposes.
Rating systems, like Amazon and Yelp - great ideas that quickly became corrupted and manipulated because people are aholes.
