Brigading

What it is

Coordinated group attacks on individuals, content, or communities — mass reporting, downvoting, or harassing to silence or punish.

How it works

A group coordinates (through private channels, forums, or implicit signals from leaders) to target a specific person or piece of content with overwhelming negative engagement. Mass reporting can trigger automated removal. Mass harassment creates a chilling effect. The target's individual voice is drowned by coordinated collective action.

Real-world examples

  • •Online communities organizing mass reporting campaigns to get someone's account suspended.
  • •Political groups coordinating to flood an opponent's social media with negative comments.
  • •Review bombing — coordinated negative reviews to destroy a product or business rating.

Ethical guidelines

  • ●Coordinated harassment is abuse regardless of whether each individual action seems minor.
  • ●Weaponizing platform moderation systems through mass reporting is a form of censorship.
  • ●Disagreement should be expressed individually and substantively, not as coordinated mob action.

How to defend against it

  • ►Document coordinated attacks with timestamps and screenshots for platform reporting.
  • ►Build a support network before you need one — allies can counter-signal during brigading.
  • ►Contact the platform directly with evidence of coordination rather than trying to respond individually.

Account Forensicsminutes

Before taking an online account's word, or taking a crowd of accounts as public opinion, spend a minute on the profile itself: its age, history, posting rhythm, network, and photo, which together show whether you are looking at a person, a persona, or a coordinated operation.

Every playbook entry states how strong its evidence is and when not to use it. Browse the full playbook.
