Abstract: The social networking service provides a method that offers communication services in which members can communicate and contribute anonymously without knowledge of the originator's identity. Since the social networking service does not accept specific identification from member users, the identification of other target services, such as e-mail, Facebook, Twitter, LinkedIn, phone numbers, and the like, will be used. The service functions as an extension to the external services for providing anonymous collaborative contributions. The social networking service accepts identification from another service and a password, and then attempts to verify the identification by sending verification code to a user identification service. The user becomes a service member once he/she confirms the recipient of the verification code to the service. A service membership is created for users who join the service.
