I love that they are weaponizing the perceived kindness of senior citizens in this way. Many of the victims of scams are some of the nicest people ever that were taken advantage of in some capacity - usually while trying to help someone. It's the digital age equivalent of staging a broken down cart and then robbing some old folks. I think most of us hate the idea of the "solution" being to not go near anyone with a broken down cart out of fear.
I'm not saying this fixes everything, but I would rather a world where scammers odds at making a living at this are so poor they won't bother versus a world where everyone has to block every number by default and live in metaphorical bunkers to never interact because you might be a scammer.
