New spam numbers are added all the time. It is possible that the phone number from which you received a spam call is not yet included in our spam directory. With a corresponding negative rating of the phone number on our websites https://www.cleverdialer.de, https://www.cleverdialer.co.uk and https://www.cleverdialer.com or in the Clever Dialer app for Android mobile phones, you can contribute significantly to further improving the quality of spam detection.
