By Debora Ely (Reuters) -A group of suspected scammers in Brazil using Instagram ads featuring deepfakes of supermodel Gisele Bundchen and other celebrities appears to have made millions of dollars through online fraud, according to police investigators. The operation marks one of the first attempts in Brazil to counter the growing use of artificial intelligence tools to manipulate images and videos of celebrities for online scams. Instagram owner Meta said that its policies forbid "ads that deceptively use public figures to try to scam people," and that it removes such ads "when detected." Another ad used the supermodel's likeness to promise a giveaway of suitcases, with buyers paying shipping fees for items that never arrived. They noted that most victims lost small amounts, usually under 100 reais ($19), and did not report the crimes.
