Mobilewalla collected data on over a billion people, with an estimated 60% sourced directly from RTB auctions. The company then sold this data for a range of invasive purposes, including tracking union organizers, tracking people at Black Lives Matter protests, and compiling home addresses of healthcare employees for recruitment by competing employers. It also categorized people into custom groups for advertisers, such as “pregnant women,” “Hispanic churchgoers,” and “members of the LGBTQ+ community.”
