One app is called Mr. Number
[QUOTE=ShootAndRoll;6591798]Would you mind passing on the name of the site or app.[/QUOTE]It's a premium app costing 4/ month or 25 / year. It can screen all calls and auto block those that may be spam, gives a deeper caller I'd, and can show reviews of that number. I downloaded it to check it out and I will delete it before the free trial runs out.
I can see a pretty harmless one word review against my number, I cannot see who wrote it, and I have not figured out how to write a review on someone else yet. I can see how this would be valuable to a provider, especially an independent.
I will keep playing with the app and eventually add more info to the OpSec forum.
