As Jake notes here, this giant data leak is from the Iron March forum, which was shut down in 2017 after being used to organize for the violent neo-Nazi group, Atomwaffen.
The @splcenter has done quite a bit of research on Iron March already -- check out this excellent article from earlier this year: splcenter.org/hatewatch/2019…
In our guide, we show you how to get this dataset (about a gigabyte, far less if you only get the CSV files and ignore the SQL database), and which files/columns are most important to use in your analysis. It's fairly simple, but takes some getting used to bellingcat.com/resources/how-… 
At the bottom of our guide, we link to a spreadsheet we started with some potential leads of self-professed active serving U.S. military servicemen who were active in this group. docs.google.com/spreadsheets/u…
Iron March was not some milquetoast conservative or irony-laden alt-right forum. It was a forum that helped spawn violence, and hosted hardcore neo-Nazi and white supremacist groups and activists. Read more about them in this piece from @jdpoulter: vice.com/en_uk/article/…
