Supporters of President Trump Donald John TrumpBiden leads Trump by 36 points nationally among Latinos: poll Trump dismisses climate change role in fires, says Newsom needs to manage forest better Jimmy Kimmel hits Trump for rallies while hosting Emmy Awards MORE have compiled a list containing personal information on thousands of people they believe are either opposed to Trump or associated with left-wing "anti-fascist" or "antifa" groups.

The list, reported by BuzzFeed, has been circulated and added to on the internet since at least April. The list, which began on 4Chan’s controversial /Pol/ board as a loose collection of names, phone numbers, addresses and social media accounts of Trump critics, has since grown into an organized document spread across the internet.

The list has also been posted on text repository site Pastebin. Several versions of the list appear to have been removed either by moderators of /Pol/, a haven for white supremacist and anti-Semitic material, or Pastebin.

The list, which is still on Pastebin, appears to violate the company’s terms of use, which bars users from posting email lists, hacked data and personal information. Versions of the list are also being hosted on other domains by pro-Trump and or far-right individuals.

Pastebin did not immediately return The Hill’s request for comment.

The list, which The Hill found and reviewed, is made up largely of names and social media accounts. But the list also includes precise details about some individuals, including their residences, hobbies and occupations.

Portions of the list were culled from names on a liberal petition that asked individuals to reject Trump and fascism. 4Chan users then pulled names from the list of people who signed the petition.

In a thread associated with the list, 4Chan users discuss some preliminary plans for how to use the list, like finding “recruiters” or a “chain of command” for ways to disrupt the groups. It’s unclear to what degree this is possible. Antifa groups, which are known for their willingness to use violence to disrupt events they see as associated with white supremacism or fascism, is largely composed of loose regional and local nodes which are informally organized and often independent of one another.

The document also targets and includes the contact information of people the list creators believe are associated with ShareBlue, a liberal media site owned by liberal political activist David Brock. ShareBlue says no writers or members of its editorial team are on the list.
