Dominick Skinner’s Irish brogue crackled on the other end of a staticky, encrypted Signal call. He told me that he is in his 30s and lives in the Netherlands, where he writes a Substack newsletter and fields tips from all over the world for his new website, called ICE List. Its mission is simple: Publish the names, photos, and social media profile links of Immigration and Customs Enforcement (ICE) agents in the U.S., more than 4,000 miles away.

Even though he is not American, Skinner sees his “accountability project” as a way to fight fascism from afar. “If we look back at history and ask what we could have done better against Hitler, or what we could have done better when Mussolini came around, the reality is that Germans and Italians couldn’t have done much, but people could have done more from the outside,” said Skinner.

Launched in mid-June, ICE List has posted information on about 50 ICE agents and local law enforcement officers. One person described as a U.S. Customs and Border Patrol photographer is labeled a “propagandist.” A donation page shows contributors—and messages ranging from “Keep crushing ICE!” to “They won’t stay hidden for long!”

This is the newest battleground in America’s war over immigration. The dramatic escalation in arrests—as President Donald Trump pushes to deport one million illegal immigrants by the end of this year—is fueling grassroots efforts aimed at thwarting ICE everywhere it goes.

Skinner is hardly alone. What began as a frenzy of ad hoc social media posts has turned into apps, hotlines, neighborhood-focused groups on Nextdoor, and websites like People Over Papers, which are allegedly trying to expose the identities and locations of ICE agents—and even the hotels where they are staying, to provoke protests and shame the hotel operators.
