My experience with spam callers that know they're violating the Do Not Call list is that they will hang up instantly if the words "Do not call" or "Remove" are mentioned.
This would be a great thing if they stopped calling afterwards - but they don't care.
This number certainly was busy bothering people back in April! Well, we got a call today...didn't answer...went to voice mail...immediate hang up without any message................. time to block another number!
It's my understanding, using VoIP and a number generator to hide actual location, robo call every number to confirm active phone numbers to sell to telemarketers and if anyone is duped into actually giving out CC info that's a bonus. Sad state when we not only don't know our neighbors lock our doors and can't let our children play outdoors and worry what's going to happen at their school, Now we can't even answer our own telephones without concern of increased telemarketing, phishing, and out and out crooks adding to our bills for fake svcs even text scams these days. Heaven forbid these nimrods use their abilities at an honest job!!!!
