I have an elderly family member with dementia who is jolted awake several times a day by spam calls and left disoriented or even at risk of a fall as a result. Telling them they don't need to answer is met with anger and annoyance (and it's not their fault). Most of the discussion here centers on seeing who's calling and making decisions based on that. There's a large group of victims that never understood those concepts, or are no longer capable of processing them functionally. The lack of tools to help us help them is very frustrating, and this is with a clamshell dumb phone, which these days is probably close to 100% elderly users with special needs.
