GANs can be used to detect this sort of thing if trained well enough. Any manipulation tool is going to leave some kind of signature. Eventually you'll end up in an algorithmic arms race, and you'll be able to fool some people, some of the time. (Pretty much the same as things have been since the Spanish-American War.) Smaller economies are going to get screwed by this, though, as they won't have the resources to fight yet another technological battle.
