Is there any way to delete inactive friends? (Solved)

I only keep 30 friends in the first place. Thats usually how far the event currency goes, and once you get all the friend point prizes, I don't see much reason to keep 100 friends. As big as some of my friends' towns were, it could take 2 hours or more to visit 100. No thanks!

And I have a few friends who havent played in years, their towns are quite small and it makes finding whatever we have to tap much easier
