The Washington Post reports on something peculiar about support for Nvidia CEO Jensen Huang online after he'd told the world he'd been unfaithful to his wife (before reports of his second extramarital affair): Joining the chorus online were voices of seemingly everyday people: a chef, a stock trader, a Hebrew teacher and several environmental activists. But at least 400 of them were fake, according to research from the nonprofit Midas Project, with links to a public relations firm involved in previous so-called "sockpuppet" campaigns... Many of the fake accounts, according to Midas Project executive director Tyler Johnston, replied to journalists, former U.S. officials and other prominent figures and backed not just Huang but Nvidia's push to sell its cutting-edge chips to Chinese firms. Like other documented influence campaigns, the posts appeared to have limited reach; the most-viewed tweet garnered about 8,000 views and 32 likes. Still, some of the posts targeted lawmakers, including accounts for the [U.S.] House Select Committee on China, Republicans on the House Foreign Affairs Committee and Sen. Elizabeth Warren (D-Massachusetts). "That's a place where you might not need a lot of views, but maybe the staffers who are running the lawmakers' account are paying attention to how their messages are received," said Johnston, whose group advocates for safe AI development... There were other clues that helped identify accounts as being part of an apparently coordinated campaign, according to the Midas Project. Some of them were created minutes or hours apart, and had user names and profile photos refreshed at similar times. They also sometimes engaged on oddly specific issues ranging from Qatar to Nippon Steel's bid for U.S. Steel and a waste management plant in Oregon.... Any one one of the posts — often replies to other posts — might have not looked suspicious in isolation. But the various clues taken together, Johnston said, gave evidence that they were linked. Some of the accounts then rushed to delete posts after he posted his findings online, and at least 260 of them have been deactivated or suspended by X.
