The countervandalism network
is a distinct group. It is neither
affiliated with nor managed by the
Wikimedia Foundation.

Documented on this page are the general procedures for countervandalism users, including local channel operators, staff and senior staff.

Channel access[edit]

Local operators[edit]

Local operators are generally trusted users both on IRC and on a local project. They have the ability to permanently voice channel users. Once a user is voiced in a CVN channel, they are able to command the bots. Some basic IRC knowledge is required of channel operators, including opping, voicing and setting flags (information also available here and here).


Staff and senior staff have channel access in all CVN channels. Generally, in respect to local authority, staff will not use their access when there are local operators available to act. However, if there are no local users available, staff may assign whatever access is required.

There is a central channel, #countervandalismconnect, which is used the best way to contact staff directly. They are voiced (+v) in the channel. Staff who are able to join multiple CVN channels may also stalk !staff. When CVN-ClerkBot is in a channel, you can use !staff and the bot pings the staff members in their channel. For basic channel operations (assigning channel flags, changing the topic, etc.), your own IRC account will have access. For advanced operations (anything requiring the +s or +F flags), log into to cvn-gc IRC account.

When staff modify access, it is important to verify that the IRC account requesting access is the correct wiki user. This can for example be done with a Wikipedia or Wikimedia cloak. This avoids the possibility of impersonation. If the user has no cloak or one that can't be verified, then ask the user to sign Countervandalism Network/Verification; the diff will then be used for any further requests. Staff may also log the action on the countervandalism wiki.


A wiki exists for coordination of countervandalism users, and is accessible to all. It is located at Here you can view the log of channel access changes and reports on various bots.

There are also two mailing lists for the Countervandalism Network:

The former is public and readable by anyone (subscribe to add messages, no confirmation needed), and is useful for updates. The latter is for coordination of cvn staff and therefore has its access restricted to approved users only.

The IRC channel #countervandalismconnect is also useful for real-time communication. Staff are voiced (+v).


A number of bots have been setup to run on the CVN related IRC channels to automate tasks and to perform maintenance. A list of the countervandalism related bots can be seen on the bots page.
