I have never had problems with people destroying my town around here... just look at wifi ratings! I let people shop at my stores, let them in to get signatures, just to visit, I would post in the train station forum saying hey anyone wanna visit? and like at least 5 each time would want to.... I understand you put a lot of work into your town and don't want it ruined, but it irks me when people never let people in to their towns or have really restricting rules/ hover on me when I visit... like you put in a ton of hard work for a reason, show it off! and everything can be replaced... I've been very open with my town to all people and lemme tell you that the overwhelming compliments have outweighed the one or two hybrids I've lost...
