A method for providing a first service as identified by a first service identifier to a user using a server system configured for connecting with a user device (2A, 2C) of the user, characterized by the server system having access to a database corrprising at least: - a first service contact identifier of a recipient required for providing the first service to the user in a manner involving the recipient, the recipient not being the user,; - a second service contact identifier of the recipient required for providing a second service to the user in a manner involving the recipient, the second service contact identifier being different from the first service contact identifier, the method comprising the steps of: - receiving the first service identifier from the user device (2A, 2C) of the user - receiving the second service contact identifier of the recipient from the user device (2A, 2C) of the user; - retrieving the first service contact identifier of the recipient from the database in dependence of the received first service identifier and the received second service contact identifier, wherein the server system further has access to a recipient requirement list of the recipient and a user profile of the user, the recipient requirement list corrprising at least one criterion regarding a spam related item of the user profile, the method further corrprising the steps of: - tracing the recipient requirement list on the basis of at least one of the retrieved first service contact identifier and the received second service contact identifier; - checking whether the spam related item of the user profile satisfies the criterion of the recipient requirement list; and - permitting the first service to be provided to the user in a manner involving the recipient if the spam related item of the user profile satisfies the criterion of the recipient requirement list and - denying the first servi ce to be provided to the user in a manner involving the recipient if the spam related item of the user profile does not satisfy the criterion of the recipient requi rement list. - a first service contact identifier of a recipient required for providing the first service to the user in a manner involving the recipient, the recipient not being the user,; - a second service contact identifier of the recipient required for providing a second service to the user in a manner involving the recipient, the second service contact identifier being different from the first service contact identifier, - receiving the first service identifier from the user device (2A, 2C) of the user - receiving the second service contact identifier of the recipient from the user device (2A, 2C) of the user; - retrieving the first service contact identifier of the recipient from the database in dependence of the received first service identifier and the received second service contact identifier, - tracing the recipient requirement list on the basis of at least one of the retrieved first service contact identifier and the received second service contact identifier; - checking whether the spam related item of the user profile satisfies the criterion of the recipient requirement list; and - permitting the first service to be provided to the user in a manner involving the recipient if the spam related item of the user profile satisfies the criterion of the recipient requirement list and - denying the first servi ce to be provided to the user in a manner involving the recipient if the spam related item of the user profile does not satisfy the criterion of the recipient requi rement list.
