    Where does the information on telephone numbers come from?

    The distribution of information on scam and spam methods is vital to oppose the leaching of people's purses. To achieve this goal tellows is aggregating a vast bulk of useful information on the caller, including his or her approximate location. The key indicator of a number's trustworthiness is the tellows score which is generated through a complex algorithm fed by your comments and ratings of the respective phone numbers. Hence, the success of this anti-fraud endeavour goes hand in glove with the community's participation. If you have experience on the matter, share it and warn your fellows before the scammers drain their pocket dry.
