    Where does the information on telephone numbers come from?

    Every information on a number is the sum of all the experience the tellows users share via comments and by rating the number according to its danger. The combination of the rating and the categorisation in the comments feeds a complex algorithm that ultimately generates the tellows-score, hence, indicating the trustworthiness of each number. However, the vast bulk of information on dangerous spam and scam numbers requires you and your willingness to share you experience and knowledge in order to help people and warn them before they suffer the inconvinience of being spammed and scammed.
