Amy Corbett was in a Zoom meeting when she spotted something strange in her own background. The black-and-white painting of a map that normally hung above her couch was no longer there. Instead, it had been replaced with a painting of an airplane propeller, a painting she had never seen before.
"It freaked me out," said Corbett, who is an Airbnb host, and had rented her apartment in Lynchburg, Va., in mid-April. Could her guest have hung a different painting in place of her map?
