The top 10 groups identified in the investigation collectively contain more than 1 million members, with totals from more top groups and pages pushing the number of members and followers past 3 million. It is not clear how much overlap there is among the groups.

The investigation will likely inform what, if any, action Facebook decides to take against its QAnon community, according to the documents and two current Facebook employees who spoke on the condition of anonymity because they were not authorized to speak publicly on the matter. The company is considering an option similar to its handling of anti-vaccination content, which is to reject advertising and exclude QAnon groups and pages from search results and recommendations, an action that would reduce the community’s visibility.

An announcement about Facebook’s ultimate decision is also expected to target members of “militias and other violent social movements,” according to the documents and Facebook employees.
