No count of participants is possible, and the estimates that circulate, from a few hundred to a few thousand loosely associated, are guesses about a network designed to be uncountable.
What is documented is the trail through criminal courts. New Zealand designated the Order a terrorist organisation in 2025. A Russian court ordered its texts banned from distribution following proceedings at St Petersburg in 2024. In the United Kingdom the anti-fascist organisation Hope Not Hate publicly called for proscription in 2020, and no decision to proscribe is recorded in the sources available for this entry. Ryan Fleming, described as heading a Yorkshire cell, was convicted of sexual offences in 2011 and again in 2017. Material by Myatt was cited as an influence on David Copeland, who carried out the London nail bombings of 1999. During the 2021 prosecution of an Atomwaffen Division leader it emerged that an Order-linked figure, Joshua Caleb Sutter, had been an FBI informant since 2003. Further prosecutions in Britain and the United States have referenced its material.
Two observations follow. The first is that the boundary between the Order as a religion and the Order as an extremist recruitment vehicle is not a boundary its own texts attempt to draw. The second is that the Satanic Panic of the 1980s, which imagined an organised criminal Satanism where none existed, has made it harder rather than easier to describe the one group that does approximate the description, because the vocabulary was spent on a fantasy, and because every other Satanist organisation, all of them law-abiding, has a legitimate objection to being discussed in the same breath.
