Making way for active neighbors

I have just rid of a lot of people in the last few days ( around 30 or so ). I believe that I do have a few forum regs as my friend. ( thanks for the taps BTW ) I do not have a cool spread sheet but the ones that I am thinking about getting rid of I tap the same Buildings every time and my name comes up for an week they are out. And I do try to get new people and when I go to there town and all I see is an GD house farm they are gone ASAP. But as for finding good friends it is just trial and error.
