A system for generating processed web address information, comprising: one or more processors configured to perform the steps: receive a request to share a webpage, wherein the request includes at least a first web address information associated with the webpage and user identification information associated with a first user; generate a second web address information based at least in part on the first web address information and the user identification information associated with the first user; share the second web address information with a second user; receive an indication associated with an access by the second user to the second web address information; in response to the indication, extract the user identification information associated with the first user from the second web address information; determine whether the first user has a status of seller based at least in part on the user identification information associated with the first user, wherein to determine whether the first user has the status of seller includes to: determine whether the first user is associated with a buyer's credit score greater than a preset threshold value; and determine whether the first user is not associated with shop information associated with a website; in the event that the first user does not have the status of seller, send a prompt message to the second user, wherein the prompt message includes a control to add the first user as a friend; and in the event that the first user has the status of seller, omit sending a prompt message to the second user; and one or more memories coupled to the one or more processors and configured to provide the one or more processors with instructions. one or more processors configured to perform the steps: receive a request to share a webpage, wherein the request includes at least a first web address information associated with the webpage and user identification information associated with a first user;
