Abstract: Techniques are described for a social networking system to provide community profiles that allow for multiple holders, editors, and/or managers. In some cases, the social networking system may be configured to distribute content associated with the community profiles based on metrics and relationships associated with accounts of the collaborators to the community profile as well as the community profile itself.

Abstract: Techniques are described for a social networking system to provide group or aggregation accounts that allow users to easily and quickly form relationships with multiple other users based on a membership association of the multiple users to the group account. In some cases, the social networking system may be configured to add and/or remove relationships based on changes in association between members and the group account.

Abstract: Techniques are described for a social networking system to enable multiple users to collaboratively create, publish, receive attribution, and/or edit content. In some cases, the social networking system may be configured to distribute the collaborative content and feedback associated therewith based on metrics and relationships between collaborators of the collaborative content and users of the social networking system.

Abstract: Techniques are described for a social networking system to provide collective accounts that allow for multiple holders, editors, and/or managers. In some cases, the social networking system may be configured to distribute content associated with the collective accounts based on metrics and relationships associated with accounts of the contributors to the collective account as well as the collective account itself.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a geographical area associated with a crisis. A first user within the geographical area can be identified based on locational data associated with the first user. Information about a safety status of the first user can be actively requested or acquired from the first user. The safety status of the first user can be broadcasted, communicated, or provided to at least a second user associated with the first user.

Abstract: In one embodiment, a method includes determining that an emergency event has occurred. The method also includes determining a geographic area affected by the emergency event. The method also includes determining that a user has entered the geographic area within a pre-determined amount of time after the occurrence of the emergency event. The method also includes sending a prompt to the user to indicate whether the user is safe. The method also includes receiving from the user a response indicating whether the user is safe.

Abstract: In one embodiment, a method includes detecting that a first set of users associated with an emergency event have posted content related to the emergency event on an online social network. The method may also include sending a safety-check prompt to each of one or more users in the first set. The method may also include determining a current-prompting probability based on one or more engagement metrics of the one or more users in the first set. The method may also include sending, in response to determining that the current-prompting probability is above a threshold probability, the safety-check prompt to each of a second set of users. The second set of users may have more users than the first set of users.

Abstract: In one embodiment, a method includes identifying an emergency event; determining that a threshold percentage of users who are associated with the emergency event have posted content related to the emergency event to an online social network; sending, in response to the determination, a safety-check prompt to each of a first set of users; determining a current-prompting probability based on one or more engagement metrics of the safety-check prompt by the first set of users; and sending, in response to determining that the current-prompting probability is above a first threshold probability, the safety-check prompt to each of a second set of users, wherein the second set of users comprises more users than the first set of users.

Abstract: An advertising campaign maintained by an online system includes an objective, and the online system determines a metric for the advertising campaign based the objective. For example, the online system determines the metric as a ratio of an amount received from an advertiser for presenting the advertising campaign to a number of completed objectives associated with the advertising campaign. Additional advertising campaigns including the objective are identified, and the online system determines metrics for the additional advertising campaigns. The online system compares the metric for the advertising campaign to the metrics for the additional advertising campaign and communicates information to the advertiser based on the comparison.
