Abstract: This disclosure relates to systems and methods for providing user content on a social network. In some aspects, the social network receives, over a communications network from a first computing device associated with a first user of the social network, a transmission including a post to be published on the social network. The social network detects, in the post, goods or services sought or inquired about by the first user, and determines a proximity of the first user. The social network identifies one or more other users of the social network located within a geographical area or the proximity associated with the first user, and presents the post only to the one or more identified users of the social network.

Abstract: This disclosure relates to restricting access in a social network. The social network stores profile information for each of a plurality of users of the social network in a database. The social network receives, from a first user of the social network, a request to invite a second user to establish a connection with the first user. The social network transmits, to the first user, one or more questions pertaining to the profile information of the second user. The social network receives, from the first user, one or more answers responsive to the one or more questions. The social network determines whether each of the answers is correct based on the stored profile information of the second user. The social network transmits, to the second user, an invitation to establish the connection with the first user when at least a number of the answers are correct.

Abstract: A server computer hosting an extended reality world receives a first transmission over a communication network from a computing device associated with a user, the first transmission including a request for the user to access the extended reality world. The server computer transmits a presentation of the extended reality world to the communication device over the communications network based at least in part on the request, and displays the presentation of the extended reality world on the computing device, where the presentation includes at least an avatar associated with the user. The server computer receives a command for the avatar to store a phrase selected by the user in a location associated with a virtual object within the extended reality world. The server computer displays, within the presentation of the extended reality world on the computing device, the avatar storing the phrase at the location in the extended reality world.
