When I started getting AARP solicitations to join, I would return the entire mailing back to them in the postage paid envelope. Not sure whether I wrote them a line or two of “free advice” like I used to do with the GOP-RNC solicitations. It took about 2 years, but AARP stopped sending anything to my address.
Bunch of inside the beltway grifters that support demonkkkraps and pretend that they represent the views of 38 million people.
We did the exact same thing. And, like with you, it took about two years for the stuff to stop showing up.
