what i do when i wanna kick a villager out is to
1. go around town to get moving pings
2. if the ping comes from a villager you wanna keep, deny,
3. after denying, save game. load it up again and then TT 6 days forward.
4. after that, TT 6 days backwards again.
5. go around town to get moving pings again.
rinse and repeat the steps until the villager you want to move out pings you. sometimes you may not get moving pings immediately after the fifth step, in that case, go find out from other villagers for rumors.
