The FBI Wasn't Good at Monitoring the Most Evident Nazis Online

Law enforcement was not just helpless to do anything. It's debatable whether or not they even realized what was happening. Most of their online efforts were spent keeping track of known quantities with long standing online ties like Don Black and his popular fascist website Stormfront. Nearly 100 hate crime murders have been traced to the site. In July of 2019 in response to a FOIA request the Bureau admitted that they had somehow lost almost all of their files on Stormfront. And if that's the case, it's probably not surprising that they completely failed to notice when fascists started infiltrating communities on websites like 4chan and Reddit.
