My dad was a subscriber. When he got dementia I eventually stopped paying for it. He lost interest. They never stopped sending it. When he went into the Alzheimers unit 500 miles away, his mail was sent to me so I can handle his affairs. It was forwarded to me. I never paid, they kept sending it. He passed , It kept coming. Then they started sending me issues, unsolicited, unpaid for. So I was getting two copies per month... Eventually They stopped. After years went by.
I have had that happen with magazines. I think I have it figured out; they want to keep up their circulation numbers in order to jack up the rates they charge advertisers.
