Facebook has asked Academics, journalists, and First Amendment lawyers to stop targeting it with the ad-targeting data tool. The researchers say the disputed tool is vital to understanding how Facebook has been used as a conduit for disinformation and manipulation.

In letter to the researchers, a Facebook executive demanded they disable a special plug-in for Chrome and Firefox browsers used by 6,500 volunteers across the United States and delete the data obtained. The plug-in lets researchers see which ads are shown to each volunteer; Facebook lets advertisers tailor ads based on specific demographics that go far beyond race, age, gender and political preference.

The executive, Allison Hendrix, said the tool violates Facebook rules prohibiting automated bulk collection of data from the site. Her letter threatened “additional enforcement action” if the takedown was not effected by Nov. 30.

Company spokesman Joe Osborne said in an emailed statement that Facebook “informed NYU months ago that moving forward with a project to scrape people's Facebook information would violate our terms.” The company has long claimed protecting user privacy is its main concern, though NYU researchers say their tool is programmed so the data collected from participating volunteers is anonymous.

The outcry over Facebook's threat was immediate after The Wall Street Journalfirst reported the news considering the valuable insights the “Ad Observer” tool provides. It has been used since its September launch by local reporters from
Wisconsin to Utah to Florida to write about the November 3 presidential election.

The tool lets researchers see how some Facebook advertisers use data gathered by the company to profile citizens “and send them misinformation about candidates and policies that are designed to influence or even suppress their vote," Damon McCoy, an NYU professor involved in the project, said in a statement.
