My mother has dementia and has gotten herself on dozens of phony charities' mailing lists. Most of them stopped their mailings when asked to do so. I have been writing to these vile people for over 2 years, telling them to STOP these mailings. They ignore everything, and keep regularly sending my mother more crap, in hopes of squeezing some more money out of her. People who prey on the elderly and disabled are the very worst kinds of people.
