Progress in the fight to block robocalls has been slow or non-existent, a new survey finds. Approximately half of the consumers who signed up for the National Do Not Call Registry, (49%) say they receive the same number of robocalls, and 19% say they receive more robocalls since signing up. The findings come from a recent survey by Clutch. Robocalls frustrate consumers, with 56% of people saying robocalls should be banned and 23% suggesting better regulation. More than 80% of people surveyed actively protect themselves from robocalls, mostly by blocking phone numbers (60%). The rest either sign up for the National Do Not Call Registry (43%) or implement a robocall screening tool (17%). The Registry, however, is ineffective because voice over internet protocol (VoIP) makes robocallers agile and hard to track. More than two-thirds of people surveyed (67%) are unlikely to answer phone calls from unknown numbers. Experts cite robocalls as one reason people don’t trust phone-based communication. Consumers who already use robocall screening services typically activate them through their mobile provider (23%) or third-party services such as RoboKiller (20%) and YouMail (19%).
