Abstract: A first user terminal receives an incoming communication via a communication system originating from a second user of a second user terminal, the second user net yet being a contact of the first user. In dependence on one or more factors relating to the incoming communication, an automatic selection is performed between: a) prompting the first user with a quarantine experience in a user interface on the first terminal upon the receipt of the incoming communication, the quarantine experience offering the first user an option to block further attempts by the second user to communicate with the first user via said communication system, or instead b) prompting the first user with little or no quarantine experience upon the receipt of said incoming communication.
