First it was seeds….now its masks being sent to citizens in Tennessee. People are now reporting receiving mysterious masks addressed from China, about a month after seeds showed up unsolicited. Law enforcement urges anyone who receives these masks to throw them away.

The United States Department of Agriculture (USDA) said it believes the seeds could be a “brushing scam,” where people receive unsolicited items from a seller who then posts false customer reviews in an attempt to boost sales. The USDA has not said whether it believes the masks could also be part of a similar scam.
