Immigration and Customs Enforcement has a certain Redditor in its crosshairs and it’s now strong-arming the social media platform to reveal who they are with a grand jury subpoena, according to a report from The Intercept. The nonprofit news outlet was able to obtain the subpoena that ordered Reddit to provide info on one of its users who’s been accused of criticizing ICE by April 14.

According to the report, ICE has been trying to identify this Redditor for a month without success. More specifically, Reddit is being asked to give up the user’s name, address, phone number and other personal data. The Intercept reported that the subpoena was issued by federal prosecutors in Washington, D.C. after a failed attempt from ICE to do the same through a federal court in Northern California, which has jurisdiction in San Francisco where Reddit is headquartered.

Reddit attorneys said their client’s posts and anonymity are protected under the First Amendment and described ICE’s use of a grand jury as “a disturbing escalation,” according to the report. Reddit didn’t state if it would challenge the government’s order or not, according to The Intercept, but it did provide a statement saying, “privacy is central to how Reddit operates and we take our commitment to protecting that seriously.” Reddit also said in the statement that it does “not voluntarily share information with any government, especially not on users exercising their rights to criticize the government or plan a protest.”

While this grand jury subpoena could set an alarming precedent, it’s not the first time a government agency has requested social media platforms reveal accounts that have spoke negatively about ICE. According to a New York Times report, the Department of Homeland Security has filed hundreds of subpoenas to Google, Discord, Meta and even Reddit again, for identifying details about its users.
