A patent granted to Apple today details a social networking system that can reliably identify friends, as well as “stalkers” and “spammers.” Under the system, a user with a relationship to another user can enter a “friend state.” However, rejections of friend requests increase a user’s “stalker count” — a user rejected a number of times within a specified time period will no longer be able to make a friend request to that same user.
Likewise, a “spammer count” is created by limiting the number of friend requests one user can make within a specified time period, making it possible to prevent additional friend requests for the remainder of the time period.
