Who keeps buying from me?

I only have 1 friend on my new account, but someone keeps buying my products and it's not that one friend. I thought you could only trade with people on your friends list?

Anything you put up for sale in your shop is fair game to anyone if they 1) visit your farm through the "Community" option, or 2) browse the newspaper when one of your items appears in it.
