Jonathan wanted to opt out everyone in his family from direct marketing campaigns, something the DMA promises is possible via their website. Surprise! It turns out the DMA doesn’t really care so much about whether or not you want to be taken off any mailing lists, and they have a rotten website and poor security protocols to prove it.
In order to make itself look a respectable and unfairly maligned industry, The Direct Marketing Association (the same people behind OptOutprescreen.com) likes to tout how greatly telemarketing contributes to the American economy. The Denialism blog scoured the DMA press releases and website found the profit they say telemarketing generates varies wildly from year to year, and sometimes within the same year.
