People may already know this but I just came across it on my personal account so thought i'd share. Basically I received a friend request from "portsmouth new hampshire" (city state), looks like it's been growing friends steadily. The account is active with many things related to the city. This could be used to build high amounts of friends, the friend acceptance rate would probably be huge as long as you're targeting the right location for your account name. You could create mass amounts of city names, post random news about the city once in awhile, then throw in your monetization site once in awhile and you'll get very active users. To speed up the friend request rate use an automated program to scrape users from pages that have to do with the city. Hope this helps you get more quality friends!
