Who data brokers are, and how they quietly sell your data
Data brokers are entities that collect and sell consumer information. The data broking industry generates billions of dollars, but it also spends most of its time in the shadows. You might not have heard any of the big representatives of this booming industry. However, the chances are, they know a lot about you. And they are not reluctant to share their insights with interested parties. Thus, let’s unveil the mystery behind data brokers, and how they manage to stay quiet about their activities.
What are data brokers, and what do they do?
Data brokers (or information brokers) are companies that collect, aggregate, bundle, and sell user data. Our digital lives leave clear trails that brokers follow attentively. Typically, they harvest information available on social media and track users’ browsing habits across various websites.
However, data brokers might have a broader selection when it comes to the information they harvest. They might attain data from public records that can later be repurposed for. The latter can allow anyone to find information on specific individuals like their physical addresses, phone numbers, relatives, age, etc.
After picking up consumer information, data brokers will use machine-learning algorithms for further processing. This automated data analysis identifies specific patterns to generate segmented profiles of people with similar interests. Thus, data brokers can divide people into precise groupings. For instance, some sets might relate to “female consumers interested in cars,” “or “20-40-year-old males living in the US.”
The generated clusters can take various details into account. It might look at age, income, general interests, stage of life, buying habits, etc. According to, such point-blank classifications might be particularly harmful to oppressed or marginalized groups. The latter includes people subjected to oppression due to their race, sexual orientation, gender, or mental ability. Thus, while a group of “rock-climbing enthusiasts” sounds innocent enough, “LGBTQ members” might not.

Immigration and Customs Enforcement (ICE) appears to have gained access to home address information to . Thus, data brokers have a diverse clientele interested in consumer data.
Inaccurate information data brokers sell

In many cases, the sold “product” might not be of the greatest quality. Data brokers might assign people to groups that do not represent them. Thus, even if businesses pay a hefty sum for reaching “cycling enthusiasts,” they might not.
Inaccuracies and poor-quality data are not fatal mistakes in this case. However, there are situations when incorrect insights from data brokers can directly affect people’s lives.
has shown just how damaging incorrect information can be. There are accounts of people wrongfully losing housing due to flawed screening processes. Typically, companies would use data brokers’ insights, or people search websites to make their rulings. If background checks rely on such information, they are bound to make unjustified decisions.
Data brokers and little to no regulation
The California Consumer Privacy Act and Vermont’s Data Broker Law do require data brokers to register with the state routinely. However, the laws that would govern these for-profit companies more actively are sparse.
Advocates against unnecessary tracking and data harvesting strongly encourage the introduction of new regulations. They need to address that most of these activities happen without explicit consent and might drastically affect people’s lives.
The potential for, stalking, or intimate partner violence are also issues requiring immediate attention. After all, data brokers typically sell data to anyone interested.

Data brokers operate massive databases by scraping public records and tracking you online. They might know your age, income, sexual orientation, buying habits, mental health, physical address, etc. Thus, it is understandable that you do not want your data harvested and sold to basically anyone.
Unfortunately, avoiding the reign of data brokers is not easy. By this point, they are likely to know more about you than some of your closest friends. A small silver lining is that you can contact data brokers and demand them to delete your data. However, with so many data gatherers around, it will take a while to confront each of them.
Lastly, you can become more vigilant about which data you release to the public domain. For instance, avoid being too open on social media. A VPN (Virtual Private Network) can also help you cover your tracks online. In essence, it encrypts information about your web traffic and masks your IP address. Thus, data brokers and various other entities online will have fewer chances of snooping on you.
