The Counter-Vandalism Unit (CVU) is a Wikipedia project whose aim is to help detect and remove vandalism on Wikipedia by using tools and experience, and to provide advice on dealing with vandals. All members of the Wikipedia community can revert vandalism at any time. Active vandalism patrollers who join this project will receive occasional newsletters with information on training, software updates, and new or modified policies and guidelines.
Some active members have volunteered to train other editors in countering vandalism. If you would like to learn more about the process or if you think you would like to train others, please see the Counter-Vandalism Academy.
