I got sober about four years ago, but the internet knows me as an alcoholic and there is in those many records out there, the fact that I have clicked on alcohol ads. I have bought alcohol online. The internet in a very real way doesn't want me to stop drinking. The fact that they know that I like to drink is actually very lucrative for them. When you think about this, this creates a really interesting ethical conundrum. It's not just that these things are creepy. It's that they're literally holding us to our worst selves, even when we try to change and work our way through the future.

The goal of data brokers is to allow consumers to decide which information may be shared with advertisers, then share in some of the revenue generated by its use. These services ask users to sign up on the Web or via an application, connect their social media and Web accounts, then ask them to answer specific questions about their interests. Based on the data provided and collected initially and over time, the brokers will place users into segments, and advertisers can purchase access to data from one or more segments for use in personalized advertising. Each time their data is shared, or advertisers purchase access to a segment in which the user's data has been placed, the user can earn points, rewards, or cash. All the data brokers note that they store their user data on the cloud using a variety of encryption and security protocols, and that the end users with whom they work can opt out of having specific data shared if they so choose.

data on demographics that are in limited supply (such as data on Middle Eastern male consumers) is more valuable than demographic data on white millennial women. Similarly, the browsing data of individuals seeking to purchase a Tesla or Ferrari automobile within the next month would be valued more highly by data brokers and advertisers than the data of someone browsing for the best deals on a used Chrysler minivan.
