    We've all had to deal with the same thing. As your phone rings from dawn till dusk and nuisance calls bask in a sun of trickery, it is the spammer and scammer that will rule the day, but nay we say!!! au.tellows.org intents to disrupt the fraudster line of success by distributing important information on all sorts of unsolicited calls. If you receive a call from an unknown number, just access the tellows database and find details on the numbers point of origin and the nature of the call. The people's ignorance is the scammer most effective advantage. Once you know who you are facing, you will also know the way to counteract their malevolent attempts appropriately. At this, the number's tellows score will tell you whether caller is reliable or dubious. The higher the score the higher the risk. Learn more on tellows-blog

    Where does the information on telephone numbers come from?

    The main indicator of a number's trustworthiness, the tellows-score, is the result of a complex algorithm that is fed by your comments and ratings on numbers. Your participation is the key to successfully counteract future spam and scam attempts since the callee knows who he or she is dealing with prior to answering the phone. Share your knowledge on the trickery of dubious entrepreneurs and help to deny them their unlawful treasure.
