Unhelpful help from "friends"

Haven't noticed that in my town. I might get the odd person who wil tap a brown house etc but one in a good few is tolerable. When I visit friends I usually tap their highest earning building available. I know people think vandalising is the best cause but if you're at 5 stars (like me) I clearly don't need the righteousness rating. That said I still welcome people to spray paint my buildings, I always appreciate it when people visit my town. But I suppose an ideal friend for me would be some one who taps my white houses, blue houses, church, etc, I.e valuable buildings.

Still though, any help is good help!
