Subscribe to Hello World Hello World is a weekly newsletter—delivered every Saturday morning—that goes deep into our original reporting and the questions we put to big thinkers in the field. . Browse the archive here Hi, everyone, Sisi Wei here (👋🏼). I joined The Markup in late August as editor-in-chief, and this week I did a fireside chat on “ ”—at a conference for people who work the digital advertising and marketing industry. Yep. Scrutinizing Big Tech inside I talked about the Meta Pixel with , managing editor of AdExchanger, and encouraged everyone in the room to and see what data it collects. Allison Schiff self-audit whether their company uses the pixel I didn’t know what kind of reception I’d get. Much of our work at The Markup scrutinizes advertising technology, and we don’t pull our accountability punches. Since we our first large-scale, crowdsourced study of Facebook’s pixel in January 2022, we’ve found websites across multiple industries— , , , and the —transmitting sensitive information to Facebook through the Meta Pixel, a Facebook tracking tool that helps site operators better target their advertising. kicked off hospitals telehealth companies tax preparation sites U.S. Department of Education There’s no question that the pixel is pervasive, but there’s good news. These stories created nearly immediate change. Many companies have either removed the pixel entirely or limited the scope of what data gets collected. So far, our reporters have collectively contacted more than a , telling them what specific information we found their sites sending to Facebook. hundred organizations We’ve received all kinds of responses from companies, but one always stands out. It boils down to: We didn’t know. Last week, our community and social media manager, Maria Puertas, and our infrastructure engineer, Simon Fondrie-Teitler, about how to be proactive about user privacy when it comes to the Meta Pixel. Here’s one excerpt I want to highlight: wrote a piece together Don’t be surprised if many people in your organization don’t know about the Meta Pixel. Many of the organizations we found leaking sensitive user information to Facebook seemed to be unaware of what exactly they were doing or the potential ramifications. —companies said they didn’t know they were collecting this kind of data from their users and promptly deactivated pixel tracking parameters. In certain cases—like that of tax preparation site Ramsey Solutions “We did NOT know and were never notified that personal tax information was being collected by Facebook from the Pixel,” Ramsey Solutions said in an email to The Markup. “As soon as we found out, we immediately informed TaxSlayer to deactivate the Pixel from Ramsey SmartTax.” Ramsey Solutions wasn’t the only organization that removed the pixel after being contacted by our reporters for comment. After we notified hospitals and health systems of the Meta Pixel’s presence, either from portions of their websites or altogether. 35 of 40 removed it Major tax companies to capture less data. The U.S. Department of Education changed its pixel’s settings to on FAFSA applicants. changed the pixels’ settings capture less information If there’s one thing I’ve learned in the last decade, it’s that unintentional harm is very common (as are unintentional bad consequences). As investigative journalists, our job is to hold people and organizations accountable for their decisions and the harm those decisions have caused, intentional or not. In addition to that, our goal is to have an impact and create real, positive change in the world. The organizations we write about aren’t monoliths—they’re made up of many people, and lots of people inside companies want to do the right thing (such as protect their users’ privacy). So, in addition to , another way we create change is by making sure our journalism helps people inside organizations who can make company-wide change very quickly. spurring regulatory action I think about it like this: If you work at an organization that uses the Meta Pixel, how can The Markup’s journalism help you to audit your own site for whether it’s sending sensitive information to Facebook and then help you fix the problem yourself? Turns out, because of the expertise we’ve gained investigating this topic, we can share a lot and in great detail. If you want a step-by-step guide, has instructions that anyone can follow, even if you don’t know how to code. Maria and Simon’s article They also have written for people who directly manage their website’s pixel settings, and who want to make changes. specific sections In the end, my talk went great, and I met a lot of people in marketing and advertising who were working toward a more privacy-first future. Because of course, just as companies aren’t monoliths, neither are industries. This should have occurred to me from the start, especially since one of the other speakers, , chief privacy officer at the ad agency UM Worldwide, got on stage right before me, cited , and ended her talk with “Check your pixels.” Arielle Garcia The Markup’s reporting on hospital websites So everyone, that’s the message I’ll leave you with today.
