This is the breakdown for incoming calls to the Nomorobo honeypot for 4/1/2018-4/23/18 that have called more than one line from 212-244-[0000-9999] (the last 4 digits change frequently, just like regular neighbor spoofing).

Data source: Our honeypot consists of over 300k lines from around the country that people have gotten rid of, mostly due to getting so many robocalls. It's the main weapon that we use to build our blacklist.
