I see a lot of people asking about how they get the data. One way is through huge data brokers that buy and sell data from retailers, merchants etc. One big company that has a huge trove of customer purchase information is Acxiom.
"The data-gathering has stirred privacy concerns. The Wall Street Journal reported in 2010 that Rapleaf, the former parent company of LiveRamp, had amassed databases tying people’s real names to privately shared information in their Facebook profiles, as well as data in their voter-registration files, real-estate titles, shopping histories, and other records. The company was censured by Facebook for the practice, which involved pulling data from apps against the social network’s rules."
It is interesting. In Sweden this would be illegal to do, unless you had consent from each individual at the time of data collection to do that type of data assembly and analysis.
