I did mention GDPR in another comment. Data extraction/portability is a 'thing' in GDPR. There is a website that has the same function, but for movies. Apologies I cannot remember the name. Similar funciton. You record the titles of the movies you watched. Thinking about this again (and this is why in my other comment I ask "who pays for this/how is that paid for"; this would be goldmine for Amazon, B&N, and other players. We also know that "FBI checking out Americans' reading habits / Bookstores, libraries can't do much to fend off search warrants" (https://www.sfgate.com/politics/article/FBI-checking-out-Americans-reading-habits-2826830.php https://www.sfgate.com/politics/article/FBI-checking-out-Ame...) No more needs for warrants!! :)
