Just last week, 8,256 people got Nomorobo protection!

Great through this last election ad cycle...I still get a couple of survey calls that ring four times...

Great Service! Thanks! Out of six calls on my phone last Wednesday four were blocked by you folks. I checked them out on Google and they were all scammers.

I think Nomorobo is the best for blocking unwanted calls. I had this service for a couple of years, but we moved to an area not supported by Verizon FIOS and are now unable to subscribe to Nomorobo.

Very pleased with RESULTS ! The larger your data base becomes, the better we like it. One of the more useful applications in our modern lives ! Thanks very much !

I admire the design, I rely on its reliability, and I much appreciate the service it provides. Now, if the FCC would just expand this to the entire Do Not Call List!! Because their list is generally ignored by the aggravators & scammers, your technology and better/faster effort by FCC to add numbers to the list, would give America have an enforced system! FCC should have paid you an award 20 times greater for your devising a solution they could not. Many Thanks!
