CHICAGO – The baseless conspiracy theory took off after an anonymous user posed a bizarre question in an internet chatroom: What if retail giant Wayfair is using pricey storage cabinets to traffic children?Self-proclaimed internet sleuths quickly responded by matching up the names of Wayfair products to those of missing children, producing social media posts that have since overrun Facebook, Instagram and YouTube.The result: A national human trafficking hotline suddenly began taking a number of calls about the imagined Wayfair scheme, stretching its resources.
