Mysterious Package of Seeds From China Brushing Scam

The Brushing Scam
The Brushing scam is exploited by a vendor and used to bolster product ratings and increase visibility online by shipping an inexpensive product to an unwitting receiver and then submitting positive reviews on the receiver's behalf under the guise of a verified owner.
People have received packages in the mail with Chinese writing and a return address in China. The package was labeled as containing jewelry but was found to have a small bag of what appeared to be seeds but were not ordered the recipients.
The investigating officer called the US Postal Inspector's office and learned that similar packages have recently been delivered to various homes across the country and is arriving on U.S. doorsteps. Therefore, if you receive any unsolicited packages from China or other foreign country, do not open them as the seeds may belong to invasive plant species. Instead, contact the USDA who will dispose of them for you.
