TheCounter-Vandalism Unit (CVU) is aWikiProject whose aim is to help detect and removevandalism 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 theCounter-Vandalism Academy.
Our goals are:
 | New Pages Patrol — reviewNew Pages to detectcopyright violations, vandalism, attack pages, hoaxes and spam, making minor improvements, and listing inappropriate pages for deletion. |
 | ClueBot NG — abot that uses a vandalism-detection algorithm to automatically revert most vandalism. |
 | Recent Changes Patrol — users who regularly patrolRecent Changes in real time and, among other things, remove vandalism. |
 | Counter Vandalism Network (CVN) — recent changes broadcasted live on IRC channel#cvn-wp-enconnect with information on how likely the edit is to be vandalism. |
 | The Anti-Vandalism Barnstar may be awarded to those who show great contributions to protecting and reverting attacks of vandalism on Wikipedia. Use barnstars sparingly – don't dilute their importance. |
 | The Silver CVU Award is awarded to those who make significant contributions to The Counter-Vandalism Unit or to counter-vandalism. |
 | The Gold CVU Award is awarded for outstanding contributions to The Counter-Vandalism Unit or to counter-vandalism where the Silver CVU Award would be insufficient. |
