Or, ignore them. If I don't talk to a particular villager for like 2 weeks, they move away. Or you could Time Travel.
Depends whether you Time Travel or not. I TT so it's quicker for me. Anyone who I'm friends with when I TT stays, but anyone I'm not friends with leaves.
Basically, the only reason I TT is to gather all my perfect fruit. I time travel three days, gather again. Time travel three days again, and so on. While I'm doing that the villagers I ignore move away most of the time. But I make sure to talk to the ones I like in between time travelling.
does anybody know if complaining about residents at town hall has anything to do with who moves out?
