I received a spoof call with a Wisconsin area code (city: Stoughton). I entered the number in one of those look-up-this-number sites and this CALLER TYPE chart showed up. While these are pretty good identifiers, I think we can do better. Add your CALLER TYPE to the "Frog Applause" page and I'll include it here.
Confession: Sometimes I pick up scam calls on purpose. I watch a lot of scam baiting youtube sites so I am fluent in obscene Hindi words.
