Unfriending Etiquette

If I visit their Springfield for a week straight and I find nothing to tap I check to see if they are still playing. If it says that they haven't played in over a week, I delete them. I like to keep lower leveled players so they can see the things I've earned/bought. I remember visiting other players and starting my " bucket list" of things I wanted to have. I'm sure EA likes the idea of "stuff jealousy" that's how they get new players to buy donuts. On that note, I'm a few shy of 100 friends now due to deleting non- players. Anyone who plays every day is welcome to friend request me.
