Exemplary methods, apparatuses, and systems receive a request from a first user of a social networking system, during a first time period, to share a content item with a plurality of second users that are connected to the first user via a set relationship. A snapshot of the plurality of second users during the first period of time is created. During a second time period that is subsequent to the first time period, a request to view content items is received from a third user that became connected to the first user via the set relationship after the first time period. The content item shared during the first time period is excluded from content items shared with the third user in response to determining that the content item is associated with the PLS and that the third user is not in the PLS. |

receiving a request from a first user of a social networking system during a first period of time to share a content item with a plurality of second users of the social networking system that are connected to the first user via a set relationship; creating a Privacy List Snapshot (PLS) for the first user, wherein the PLS includes the plurality of second users of the social networking system that are connected to the first user via the set relationship during the first period of time; receiving, during a second period of time, a request from a third user to view content items, wherein the second period of time is subsequent to the first period of time and the third user is connected to the first user via the set relationship subsequent to the first period of time; and excluding the content item from content items shared with the third user in response to determining the content item was associated with the PLS and determining that the third user is not in the PLS. |
