Don’t encourage people to leave
You have up to ten villagers on your island. Obviously, there’s a good chance one of them will be a stinker. For every awesome character like the psychotic mouse, Bella ,or the ready for action squirrel, Agent S, you’re going to find the occasional trash beast. For example, I was “blessed” with a ram in full clown attire named Pietro. He was horrible and I wanted him gone.
Here’s the thing, if you want someone gone, just be patient. The popular thing to do is to bop them a bunch with the net over a couple of days, hit up Isabelle and report them, ignore them or even write them nasty letters.
First off, this method has some pretty bad side effects. Treating a villager poorly has a ripple effect. Let’s say you have a villager you absolutely hate, I’ll name him…Pietro. And you have a villager you absolutely love, like Kabuki. You treat Pietro poorly and there’s a chance he’s vent his frustrations to Kabuki. Now your relationship with Kabuki is also rocky because Kabuki thinks of you as a monster. You are, but still; you don’t WANT to be.
Instead, just be patient. You can only have 10 people on your island that aren’t you. When that happens your campgrounds are going to become your best bud — especially if you have some of the Animal Crossing amiibo cards. If you have a full island and convince someone from your camp to come visit, they’ll bring up the fact that your island is full but then ask if you’d like to ask someone to leave. You pick Pietro and guess what happens the next day? No more clown ram. It’s gone, back into the sewers from whenst it came.
Minimal effort from you equals maximum efficiency. If you don’t have amiibo cards, just wait until someone visits your camp and convince them to move. Even if it’s not the one you want, consider if they’re better than who you have. Definitely not a metaphor for our political situation.
