    Where does the information on telephone numbers come from?

    In order to achieve our goals it is imperative to sum up every information available on the callers. That's when you come into play. By sharing your knowledge on spam and scam numbers in form of comments and your ratings you feed a complex alghorithm that not only produces the tellows-score but also gives advice on the trustworthiness of the numbers calling you. But at the end of the day, it will your participation that will generate the amount of information needed to save people before they suffer the consequences of being scammed. Share your knowledge and, therewith, negate the scammers greatest advantage that is the people's ignorance.
