Casby, I understand. Recently, I unfriended someone whose town made me nervous. I guess I was afraid of guilt by association? Anyway, this town had many duplicates of unique (one per town) buildings and decorations. I didn't care how they got all of it, or why, I just didn't want any part of it.
I buy donuts all the time, so I know how quickly they can speed up an event. But even a "Boatload" of donuts can only buy so much. And no amount of donuts should be able to buy doubles (triples, quadruples,) of certain items. (I'm talking MANY unique buildings.)
I've only come across one such (I guess "illegal") town since I've started playing, but that was one more than I was willing to accept.
I would never do anything to get anyone in trouble. I simply unfriended this person.
It just made me feel WAY TOO uncomfortable.
