Selective information sharing between users of a social network

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• receiving, by a server from a first terminal associated with a first user, a self-select stock acquisition request, wherein the self-select stock acquisition request comprises information of at least one self-select stock and a first location of the first terminal;
• receiving, by the server from a second terminal associated with a second user, a response message responding to the self-select stock acquisition request, the response message comprising a recommended content information pertaining to the at least one self-select stock and a second location of the second terminal, wherein the recommended content information corresponds to stock recommendation information provided by the second user in response to a query regarding the at least one self-select stock received by the second user from the first user;
• determining, by the server, that (i) the first location of the first terminal and the second location of the second terminal are within a preset range, and (ii) a first time of the self-select stock acquisition request and a second time of the response message are within a preset time difference;
• and
• in response to determining that (i) the first location of the first terminal and the second location of the second terminal are within the preset range, and (ii) the first time of the self-select stock acquisition request and the second time of the response message are within the preset time difference, transmitting, by the server to the first terminal, a target content associated with the recommended content information of the response message, wherein the target content is a recommendation associated with the at least one self-select stock.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• receiving, by a server from a first terminal associated with a first user, a self-select stock acquisition request, wherein the self-select stock acquisition request comprises information of at least one self-select stock and a first location of the first terminal;
• receiving, by the server from a second terminal associated with a second user, a response message responding to the self-select stock acquisition request, the response message comprising a recommended content information pertaining to the at least one self-select stock and a second location of the second terminal, wherein the recommended content information corresponds to stock recommendation information provided by the second user in response to a query regarding the at least one self-select stock received by the second user from the first user;
• determining, by the server, that (i) the first location of the first terminal and the second location of the second terminal are within a preset range, and (ii) a first time of the self-select stock acquisition request and a second time of the response message are within a preset time difference;
• and
• in response to determining that (i) the first location of the first terminal and the second location of the second terminal are within the preset range, and (ii) the first time of the self-select stock acquisition request and the second time of the response message are within the preset time difference, transmitting, by the server to the first terminal, a target content associated with the recommended content information of the response message, wherein the target content is a recommendation associated with the at least one self-select stock.
