Nomorobo is service that works with VoIP services that allow simultaneous calls so you can allow your calls to go to its server also. It then white or blacklists your calls, with the goal of ending robocalls to you (either you hear a blip ring or no ring when it works.) I am interested in using the service (it is free, by the way) but I am concerned of it selling data on me and actually causing more solicitation problems. It would know who is calling you, as it receives your calls, and it would know times of days when you general answer your phone versus letting it ring or go to mail. That would be very valuable data (for example, knowing you answer phone between certain hours and not other hours, and knowing that you are getting a lot of calls from financial institutions or real estate agents would pin point services, that you are seeking now, that could be sold to you via traditional cold calling by an actual person, calls which would not be blocked by Nomorobo as they are not robocall center oriented calls.) Marketing companies would likely value that data above must marketing data. The founder stated that the business goal is to prefect the service (more users leads to more data on robocalls centers allowing their blacklist to grow) and then sell subscription to businesses while keeping consumer service free. Even if he is being straight forward, he is receiving outside, Angel investment, money now, and those investors might have different ideas and that more pin-point data his service will compile on users would be very valuable marketing data to sell. Anyone know anything about Nomorobo? Any problems you see? I might sign-up for it, and give my real phone number, which they require, plus assign their number to my actual phone carrier so my calls can ring simultaneously there but give a fake name so if I start getting calls asking for that name or mail addressed to that fake name, I would know they sold my data.
