I totally understand what you mean. But unfortunately there's no such trend for those junk call numbers (yeah, they are smart but annoying)

But I still want to give you a big hat off and show my appreciation
I tried inputting a hundred numbers in blacklist before. It drops the call from the blacklist immediately. Very nice!!
And then I spent "some" times to input all those junk numbers (eventually it's around 10k numbers) to blacklist, the call from the blacklist drop by the app with just two rings. Considering the huge and long blacklist, it's very efficiency call blocker. I like it very much

The only things that I want more from 0.0.3 (if you have time of course ) is the ability to view the list of blocked calls and to search from the blacklist so that I can add the numbers and maintain the database from this ground
