Via email Bob Reynolds points out:
Here’s one for the “Jews in the attic” category: http://komonews.com/news/local/king-county-using-grocery-store-data-to-target-pet-owners
From the article:
“This is not King County going and grabbing this data, you know, big brother watching what you buy at the grocery store,” said Satterfield.
Instead, the county said they pay the company who pays stores such as Safeway and QFC for access to customer data contained in every one of those reward card swipes.
Satterfield seems to think that paying someone to do it for you means you are “not doing it”.
From my Jews in the Attic Test web page we have an example which predicts the result Bob points out:
Elimination or severe restriction of anonymous financial transactions. The purchase of food and other supplies for your “Jews in the attic” would show up in the records as being excessive compared to what your needs were.
