Facebook on Friday removed what it called a global network of more than 900 accounts, pages, and groups from its platform and Instagram that allegedly used deceptive practices to push pro-Trump narratives to about 55 million users. The network used fake accounts, artificial amplification, and, notably, profile photos of fake faces generated using artificial intelligence to spread polarizing, predominantly right-wing content around the web, including on Twitter and YouTube.

It represents an alarming new development in the information wars, as it appears to be the first large-scale deployment of AI-generated images in a social network. In a report on the influence operation, researchers from disinformation groups Graphika and DFRLab noted that this was the first time they had seen the technology used to support an inauthentic social media campaign.
