AARP's magazine and bulletin[1] are pretty much filled with scam-awareness articles every issue. It's an absolutely major concern.

It being a major concern doesn't mean there's any solution around said concerns. Give me 100 old peoples phone numbers and I bet I could convince 10 of them that I am AARP trying to make them safe and eventually get money out of them.
