You brave soul.
i too made that mistake once.
i only went there once after i bought it and someone yelling at me in spanish or some language close to it was trying to bully me into giving them free items and bells by not letting me leave. wifi switch and left that horrible horrible place.
LOL. It's not so bad. Some people are actually nice. And I think you can block people you don't like so they'll never be on the same island with you again.
Trust no one, don't let them into your town, they look like people, but their all Thiefs.
