More likely she had clients simply deliver food to her place, lots of different clients at the same location, it would send red flags to the fraud detection algorithms. Rather than have a system in place asking clients if they chose that delivery they just silently ban the address. (Yes, I read the thread and how she had the food sent to another place, that could've been the triggering event for the algorithm.) She should just list her place on AirBnB and it would probably be sorted.
