That March 16 tweet, directed to a Hawaii congressman, was not the work of an American voter venting her frustration. The account, “@AliciaHernan3,” was what disinformation researchers call a “sock puppet” — a type of fictitious online persona used by Russians when they were seeking to influence the 2016 presidential election.
But it was Iranians, not Russians, who created @AliciaHernan3, complete with a picture of a blonde woman with large, round-framed glasses and a turtleneck sweater. It was one of more than 7,000 phony accounts from Iran that Twitter has shut down this year alone.
