Such scam ads have proliferated on right-wing websites worldwide in the past eight months. They use fake endorsements from celebrities including Winfrey, country music singers Dolly Parton and Reba McEntire, Twitter and Tesla owner Elon Musk, actor Ryan Reynolds, Canadian prime minister Justin Trudeau and former German chancellor Gerhard Schröder to promote dubious medicines and cryptocurrency frauds. Conservative publishers make money from each click on a deceptive ad, exploiting their like-minded readers.The ads were placed by AdStyle, an ad network whose corporate website lists it as being registered in Delaware with an office in Boca Raton, Florida. Its website said it is "trusted by" major brands including Toyota, Ikea, EA Games and L'Oréal. But Florida and Delaware corporate registries have no record of AdStyle, which appears to be operated by a Latvian couple living in Italy. Spokespeople for Toyota, Ikea and EA Games said they could not find any records of those companies working with AdStyle. L'Oréal did not respond to queries."These ads are certainly terrible," said Kirsten Grenier Burnett, a spokesperson for McEntire. Spokespeople for Trudeau, Musk, Reynolds, Schröder and Parton either did not respond or declined to comment.
