Is this thing on? – Numbo: Scam Call ID & Lookup Review

Have to say I am disappointed with this app in a couple ways. First, I haven't noticed any calls being blocked. I'm still getting tons of spam calls. Perhaps I am using it wrong? Second, I had hoped to see integration, where perhaps when I have answered a spam call I could hit a "send to blocker" button to add it to my list and share it with others?
