How do you recognize brigading in a comment section?

Brigading refers to the coordinated mobilization of users from outside a community to vote, comment, or otherwise disrupt a thread, typically to punish a post or user that another group dislikes. It is a form of vote manipulation and violates Reddit's policies. Recognizing it — especially as a reader in a thread being brigaded — helps you interpret what you are seeing accurately rather than mistaking coordinated behavior for organic community response. Several patterns indicate possible brigading. The most obvious is a sudden influx of new or low-activity accounts all posting very similar comments within a short time window. If you sort comments by New in an otherwise normally paced thread and see dozens of accounts all posting for the first time within the same hour, all expressing the same viewpoint with similar phrasing, external coordination is likely. These accounts often have very little post history, were created recently, or have posting patterns entirely outside the community being brigaded. A related signal is a dramatic, sudden vote shift inconsistent with the thread's prior trajectory. A post that was steadily accumulating upvotes and then abruptly swings to a negative score within an hour, without any obvious catalyst within the thread itself (such as a factual error being discovered), may indicate a coordinated downvote campaign. Brigading often originates when a post or user is shared in another community, a Discord server, or an external platform with a call to action. Mod teams can check account creation dates and posting history to verify this pattern, but as an ordinary reader you can only observe the surface-level symptoms. If you suspect brigading, the appropriate response is to report it to the community's moderators rather than to engage with the arriving accounts. Moderators have access to tools that can identify coordinated behavior and can flag it to Reddit's administrators.
