I am seeing someone posting facilities and sending ingredients who is neither a buddy or a neighbor, and is not even a friend in Facebook. Her name is "Darlene" and she goes by "Zena" in the Marketplace. I've attached a pic showing her activity with a "Manage" link, but when I click it confirms she isn't neither neighbor or buddy. So I don't know how she can even see my requests, much less work them?! Is she a hacker? I don't know how to get rid of this person. Help?
