I've already used that feature in the past to troll on my fathers congregation. The funny part is that my dad was the assigned minister to response to my fake request.
I must confess that I need to control myself a lot to not laugh when my father share with me the unpleasant experience to made a few kilometers to find a specific house and after a conversation with the house owner he realized that was a prank and he have to apologize to the owner.
The address that I used was a small office so it's easy to find online the address and the full name of the owner.
After that I repeated the prank two times, but I don't have any feedback because maybe the task was assigned to other publisher on that congregation.
