Embodiments of the present disclosure provide a method, a system and a server for removing alerts. An example method includes monitoring an alert removing instruction triggered by a current user for alerts in a social application client. An alert removing request of the current user to a server is initiated according to the alert removing instruction. Alerts triggered and returned by the server are received according to the alert removing request of the current user, with the alerts returned by the server being obtained by removing a group of alerts designated to be removed from on-going alerts in the social application client. The alerts in the social application client are updated as the alerts returned by the server.
