Hitting the villagers or complaining to Isabelle doesn't work. Ignoring them or talking to them until they get creeped out works best.
These don't work. At all. Complaining to Isabelle just resets their clothing and phrases. Ignoring or hitting them also doesn't work. Most of the villagers that wanted to leave my island were the closest to me. So this whole article is just fake news tbh.
Also, there ISN'T an application selection in-game. That was just a misunderstanding of what Nook's quote referred to, and the only selection processes are through tours and the campsite. As for forcing a villager out, the only proven method in this "guide" is campsite/amiibo.
Still waiting for that source on Isabelle. It's also debatable if abusing a villager has EVER worked in moving them out; players have been doing that for almost 20 years with no consistent results. Did it suddenly change in NH?
Do you have a source on complaining to Isabelle actually working? Because complaints never affected moving chances in previous games. All they ever did was reset an animal to their default appearance and catchphrase, as a fix in case another player made it obscene.
