The little furniture doesn't bother me, but everyone with a different license tag certainly does. Why are you hesitant to report this? Report it and then the ball's in the authorities' court.
I'm just observing what's going on and I guess I just didn't want to cause grief in these people's life because of my fears and some sense of paranoia. That's why I'm sharing this here to gain a better perspective. I will report what I've seen.
