Reddit, Meta, and Google voluntarily “complied with some of the requests” for identifying details of users critical of Immigration and Customs Enforcement (ICE) sent as part of a recent wave of administrative subpoenas the Department of Homeland Security has been distributing to Big Tech the past few months, according to an anonymously sourced New York Times report.

Those three companies, plus Discord, have received “hundreds” of such requests that have come from DHS recently. Meta, it should be noted, is the parent company of Instagram, Facebook, and WhatsApp.

Administrative subpoenas used for this purpose represent an escalation. This tool, which comes not from a judge but from DHS itself, was formerly reserved for situations like child abductions, according to the Times.

The users were targeted because their posts “criticized ICE or pointed to the locations of ICE agents,” the Times says.
