Rebecca (Becca) Rick's has published a highly informative interactive graphic (along with the data source) detailing the Paypal data sharing efforts, in which, your data is published to a multitude of said entities. Astonishing.
Folks, the easiest method to explore this super-graphic is to click this post's title, or the "published" link above, and magically visit the interactive graphic on Ms. Rick's site. Rated Highly Entertaining by Infosecurity.US!
Thanks for the H/T!
