Over the weekend, The New York Times and The Observer revealed that Cambridge Analytica paid to acquire private information on more than 50 million Facebook users, reports CNBC, which added that the information allowed the firm to provide services to then-candidate Donald Trump’s election campaign, “including creating “target audiences for digital ads and fund-raising appeals, modeling voter turnout,” and more, according to the report.

“It’s yet another reminder that what you do on Facebook might not always be as private as you think.
