I was so worried that this would be an april fools, haha. He'll move out soon enough if you're nicer to him, villagers tend to want to move out the more friendship level you have with them. If you ignore them chances are if he does ping he'll say he wants to be better friends before he'll leave. Although you can just exit the game and reload it if he changes his mind when he does eventually decide to move. I will admit though he is a pretty scary villager, he looks like he's just come fresh from jail LOL.
