A concentrated effort by one online group to manipulate another. (e.g. by mass commenting)

When people from one group, organization, fandom, forum, server, etc. aggressively infiltrates, usually spontaneously, a rival forum, server, or stream; negative criticism is usually given to the victim of a brigade (the event itself sometimes being called a raid), with insults and counter-signaling common. Usually used in the past participle ("brigaded"). Brigades can be done in good humor, but are usually antagonistic in nature.

Brigading is an online harassment tactic where a group of people rally against an individual (or occasionally against a small group of people) in a coordinated, sustained and organized way.

When few hundreds of devoted and educated men decide to go on an internet crusade to make this world a better place, rarely appreciated or thanked. Those heroes work in silence so normies culture is disrupted and prevented from taking over the internet.
