Do you have standards?
I'll start. I usually keep around 30 neighbors so I can properly watch (spy) on their farm progress. I'm up to thirty instead of 20 because if coin farming but I like the neighbors I have.
Forum Discussion
For my primary town, I prefer neighbors who keep their vandalizable buildings accessible, neighbors I've "met" on this forum, and neighbors with whom my Springfield grew. For my secondary town, I like to have neighbors who appear to be having fun with their Springfields. You know, elements of humor, character farming, some design elements present, and the like. Inconsiderate neighbors I delete. For instance, those who have huge, empty spaces as the 1st encounter (on purpose) or have profane messages etched in foliage or shrubbery, etc. We can no longer learn who visits, but if someone hasn't logged on in a week (and there are no reports of server problems), I usually delete or consider deleting.
