Twitter unveiled a plan Tuesday to curb the spread of manipulated content including "deepfake" videos as part of its fight against misinformation that could result in violence or other harm. The policy was announced after the platform asked for comments last year on ways to reduce "synthetic and manipulated media" that could deceive people during election campaigns or provoke violence or physical harm. Twitter, which, along with other social media, has been struggling to respond to concerns over misinformation, said its new policy calls for a mix of warning "labels" for tweets that included manipulated images or video and removal of the tweets. The move comes amid growing concerns over "deepfake" videos altered using artificial intelligence, along with other kinds of manipulation to deceive social media users. gc-rl/ft
