On February 20, 2006, a GAME VIRUS threat made by some hackers started circulating around the Internet saying that they would go into people's towns on Wi-Fi and destroy them by turning their town gate into a museum, preventing any Wi-Fi play or destroying their towns, making it so they can not receive any special visitors, evict all neighbors, prevent new neighbors from moving in, and other threats, such as recklessly chopping down trees. These hackers can supposedly go to others' towns without knowing their friend code and wreak havoc. The integrity of this threat is debatable, as nobody really knows who started it. "prguitarman" of Livejournal has described a method to get rid of the museum gate glitch which involves destroying your town and moving to a new one.[1] The AnimalMap editor can be used to correct these problems, without destroying your town. Although, a more common act of present day hackers is to "hack" different items. By doing this, they are able to receive any item of their choosing, including the rare Mario Items which have partially been handed out for Nintendo Wi-Fi events by Nintendo. They then can sell these on Wi-Fi and make money. There is also a way using Wi-Fi to duplicate, or "dupe", items they already own, including money (Bells.)
Several users have reported that burying something too close to your town gate and saving the game can also cause the 'Museum Gate' glitch.
