看了英文报道。怀疑是brushing scam

Jane Rupp, president of the Better Business Bureau's Utah chapter, told KSTU that she suspected the packages could be a scam called "brushing," in which third-party sellers send recipients items they didn't order so that they can write a positive review on their behalf while posing as a verified buyer.

"That is rather random. I don't think I've heard of seeds before," Rupp told KSTU. "The first thing to do is Google your address and see what's out there ... Numerous things will come up when you Google your address. It's kind of scary sometimes."
