I just dealt with this scam you guys are talking about and yea... its pretty sneaky. I bought a item on Poshmark and within a day realized it was a listing with stolen pictures so I tried to cancel but he had already notated a tracking number. It sat until the last hour of the 7th day before he shipped it ... (7th day I could have canceled). So it makes it to my town and shows delivered and whaddaknow there is nothing in the mailbox. Had my post office buddy run the tracking and ended up .... now get this.... The tracking # was assigned to my address but the package had an address on my street one block down and the name was my first name and a fake last name. Thankfully I am in a small town and we can still knock on each others doors so I retrieve the package but only because I got to see the address on the form at the post office. You see... since it was not my name they couldnt release any information for me to use to show Poshmark. So yea... had I not had connections and live in a town where we are all friends I would be sitting with nothing to show but that it was delivered in my town.
