I have been playing since June and exchanging rare fruit with my sister's town, but she doesn't want to play as often as I do, so I'm looking for new friends.
My question is about town safety. In ACWW, there were problems with inviting in strangers because they could drop a mysterious item that would destroy your town. I don't know if that was just a rumor or a real thing, but does something like that exist in New Leaf?
Also, in addition to the WiFi switch, if you host the trade at your town, you can end everything as soon as the trade is done if you don't want people wandering around. If you push the start button, there's an option called End Session.
