The Background
Thanks to an anonymous online leak of data and materials from influential Neo-Nazi website Iron March where the white supremacist terror groups Attomwaffen Division, Vanguard America, and National Action formed, we were gifted with a trove of identifying information about Iron March. The released information includes a full copy of the Iron March content including usernames, user’s posts and links, along with sensitive details such as the email and IP addresses used to register usernames, plus private messages. All of that data, including the information shared in the private messages which include personal details are the framework with which we use to identify users. You may view an online version of the leaks built by Jewish Worker here.
Iron March user “Brotheryellow” has been identified as none other than David Jonsson, who is last known to be residing and working in Belvidere, Illinois.
David made this pretty easy. He used his real name in his real email and uploaded a picture of himself. Here’s his user profile from the Iron March forum. We’ll dive in to that later.
“Brotheryellow” spent more than a few months on the fascist forum. He made several anti-Semitic remarks, and discussed reading Neo-Nazi literature. David admits to reading White Power a piece of Neo-Nazi literature written by American Nazi Party founder George Lincoln Rockwell.
He has defended the “alt-right“, the name of a loose umbrella of fascist and racist organizations across the country that organized primarily online and came together for the deadly Unite the Right Rally, among other rallies.
He also links to a now defunct Neo-Nazi podcast called Weimerica. The domain name for the site listed is now gone, but we can gain a hint on what the podcast is about by looking up what the Neo-Nazi idea of Weimerica entails.
From the alt-right glossary:
“Weimerica
(a pormanteau of Weimar Germany and America) refers to the alt-right’s view of contemporary America as a new iteration of Weimar Germany. Often, alt-righters who use “Weimerica” will refer to the progressive trends in America and compare them to Weimar Germany for not being white, racist and Christian enough”
He also makes several anti-Semitic comments in the forum [1, 2]. His most public racist and fascist musings come in the form of his YouTube videos, which have very few views, but give us a deeper look into his obsession with racism. All of his videos have been archived, so even if David takes them down, they are still around.
The Trace
As we mentioned above, David used the same email to sign up for Iron March that he does for his realty business at Advantage Realtors in Belvidere [archive].
Additionally, an anonymous eagle-eyed comrade uncovered more information on David Jonsson, including his article on the Deaf and Hard of Hearing [source, archive] website, where he says he runs an internet marketing company “Brotheryellow:” 
David Jonsson also has a blank Fine Art America profile [source, archive]
And finally, David’s Quora profile [source, archive] where he answers questions about deafness and running:
In 2013, using some mind-boggling mental gymnastics, David is casually transphobic in an attempt to create more deaf and hard-of-hearing acceptance:
And that’s the Iron March user, Boone County resident and known fascist David Jonsson.
Due to the publishing requirement of this platform, we cannot post personal information like addresses. However, redacted information about David can be found here.
