The connection engine finds and follows three types of people: i) people in the same industry as you (based on the industry in your profile); ii) people within a 25 mile radius of your location (based on the location in your profile); and iii) people that you have imported into your address book (if they are members). When looking for people to follow, the connection engine also excludes two types of people: i) people who have been tagged as spammers by our anti-spam team; and ii) people who have previously been manually unfollowed by you.
