I have had 3 sales within an hour (after not selling any for months). All are from accounts created today with no reviews etc. All going to the same area. Is this a possible scam?
It's certainly very odd but no way of knowing for sure or what the scam might be. You'll have to go with your gut. If you're worried cancel the transactions using the reason "Problem with buyer's address" (the nearest one we have), and put the IDs on your blocked bidder list.
