From that link:
> The company was censured by Facebook for the practice, which involved pulling data from apps against the social network’s rules.
Sounds like they just ran an app and misused the API? Are FB and Google really allowing this kind of stuff? Random companies like United, meh I don't expect them to have much scruples. But Google and FB?
Any info on which banks/companies do this? Does it happen with debit cards, too?
That's not even close. That's CC companies selling aggregated data. That generally won't identify a user, to link their CC purchase of a watch with watch related ads. (Unless they were the only customer in that region.)
The link says MasterCard sells info on which ZIP codes have which purchases. That's extremely different than offering a cookie (or somehow identifying) to say "this guy bought a watch".
They used their OWN data. I.e. purchases in their store. They buy other records to supplement. Can you point me to the quote in that article that says Target buys a list of purchases _from other merchants_ via the CC processor?
