In the Animal Crossing: New Horizons game for the Nintendo Switch, what can online users visiting via a Dodo Code do on my island?
I'm particularly interested in any sort of "griefing" behavior I should be aware of before I open my island to strangers. I'd like to know the risks before I share a Dodo Code on social media if I have e.g. a good turnip sell price.
It might also be helpful to know if there are differences in what visitors can do when they are considered friends or "best friends".
