Neighbors not in Stonecutters event: Tapping or passing by?

Over the weekend I deleted the people who hadn't started building their lodge yet. As of now I have a couple people who've build the lodge but haven't come posted homers four hour task to give me the ability to spy on them so they'll get deleted tonight when I do my rounds. I have a couple friend requests waiting to be accepted so I have no problem deleting inactive players. I want neighbors who play everyday and will visit me as often as I visit them.
