It takes me far more time to sort through all the crap I get in my mailbox delivered by USPS. I either don't answer the call, or hang up 5 seconds after answering. In general I worry that blocking legitimate "robocalls" will make people miss important events. My mortgage company was trying to contact me and the phone was displaying "Spam Likely". Another instance last year was my city sending out an emergency alert for a hurricane.
