Wikipedia:Cleaning up vandalism/Tools Information

From Wikipedia

The following is a list of tools and resources available for those who want to clean up with a more systematic approach.


Screenshot of Wikipedia recent changes IRC feed

The old school way is to load recent changes and check the (diff) links. It can be filtered according to featured articles, good articles, living people, new editors' contribs, IPs' contribs and mobile contribs (as these are more prone to vandalism, see Help:Recent changes). Searching for articles by their namespace and specific tags (e.g. VisualEditor, possible BLP issue or vandalism, etc) can also be done. If they contain harmful edits, you revert to the previous version. However, the high volume of edits that occur each second makes this difficult to accomplish most of the time, and several tools have been created to simplify the process:

  • DoubleCheck, aka WikiLoop DoubleCheck a web app for monitoring and labeling revisions. When labeled as "Should Revert" and is revert-able, it provides a quick link for user to go to Wikipedia to revert that specific revision. Direct link to the app:

  • Huggle is a fast diff browser which parses edits from users and sorts them by predicted level of vandalism. Once identified, malicious edits can be reverted in the click of a button. Due to the fast-paced nature of the program, users on the English Wikipedia must have the rollback permission to use it; however, this is not a requirement on other wikis.
  • IRC Bots reporting at the #cvn-wp-en connect channel on the freenode network list suspected vandalism edits (for example: blankings, edits made by blacklisted users, etc.) (Use this link to open the IRC channel on a web browser.)
  • Lupin's Anti-Vandal Tool monitors the RSS feed and flags edits with common vandalism terms. It also has a live spellcheck feature. This tool works in monobook skin only.
  • RCMap - Geolocates anonymous edits from the IRC live feed and displays them on a world map, with links to diffs. Supports multiple languages in a unified interface.

  • RC Patrol - a lightweight script that makes it easier to patrol recent changes. After installing, visit this page. The script uses ORES to automatically determine whether the edit needs review. You need rollback or admin permissions to use the script, just like with Huggle.
  • RedWarn patrol can be activated by any user of RedWarn on the recent changes page, quick reviewing and one-click rollback of disruptive edits.
  • Snuggle is a browser-based newcomer observation and support system, introduced in 2013. It gives a compact visual display of edits and talk page entries for accounts whose first edit was made within the past 30 days. It can be used equally to welcome well-intentioned new editors or to monitor problematic ones.
  • SWViewer ( direct link) is a user-friendly webapp with simple and intuitive UI that enables you to monitor recent changes in real-time. It also provides features to monitor multiple wikis at the same time. In order to use the application, rollback permission is required.
  • WatchlistBot is an XMPP bot that sends messages in realtime when articles are modified. Users with a Jabber account can subscribe to the bot and watch both articles and users.
  • WikiAlerter, a Windows program for patrolling new pages, and deleting/tagging them. Designed primarily for CSD, but supports AfD and ProD. Currently in beta, but there is a release.
  • WikiGuard is a Mac OS X program that monitors the IRC feed and attempts to approximate each edit's risk.
  • WikipediaVision is a web-based world map visualization of unregistered edits to the English (and the German, French, Spanish, Swedish) Wikipedia, almost the same time as they happen.

Rollback tools

These tools extend the rollback feature by allowing you to specify a summary when using rollback. They may also offer additional features:

Rollback-like scripts

These tools can be used to achieve the same effect as rollback if you do not have it.

  • Navigation popups are a set of utilities that appear when hovering over wikilinks. Particularly, hovering over links of old versions provides a "revert" link.
  • Twinkle gives both non-administrators and administrators three types of rollback functions. Other functions include a full library of speedy deletion functions, user warnings, pseudo-automatic reporting of vandals, and more.
  • RedWarn, like Twinkle, gives both non-administrators and administrators nearly twenty types of rollback functions, including a "rollback preview" and "quick rollback".
  • mobileUndo ( new version) a script which allows you to revert when using the mobile interface.

Special pages

Task Forces

IRC channels

Note that these are not operated by or affiliated with Wikipedia.

  • #cvn-wp-en connect Primary RC bot listing (Activity feed only, discussion takes place in #wikipedia-en connect)
For a list of bot commands, see CVNBot Documentation. To use these commands, you must be voiced, which requires NickServ registration and an invitation from local operators or #countervandalism connect.
  • #cvn-unifications connect Account creations
  • #cvn-commons-uploads connect File uploads
  • #cvn-wp-en-cluenet connect Channel that reroutes information from ClueNet. (Read-only, only staff and bots can speak)

Vandalism Detection Score Services

  • WMF ORES is a web service and API that provides machine learning as a service for Wikimedia projects maintained by the Scoring Platform team. The system is designed to help automate critical wiki-work – for example, vandalism detection and removal. Currently, the two general types of scores that ORES generates are in the context of “edit quality” and “article quality.” [1]
  • ClueBotNG Score
  • STiki Score


  • Template:Vandalism information, a tool used as an indication of the current overall level of vandalism that is taking place on Wikipedia. On the page, click the edit button below the vandalism meter to change its level from 5 to 1 and/or add a short comment; 5 indicates very low levels of vandalism, and 1 indicates extremely high. You can add the vandalism information template to your userpage to stay up to date. See Template talk:Vandalism information for different styles.
  • Countervandalism Network, volunteer group that operates the "#cvn-" channels. This group is not owned by or affiliated with Wikimedia Foundation.
  • Wikilink scripts enable you to double click on [[wikilinks]] within IRC clients. Useful if doing patrol on the IRC channels.
  • There are other scripts that may be handy while doing cleanup (not necessarily vandalism cleanup). Check them at WikiProject User scripts/Scripts ( WP:JS)
  • Template:Toolbar experiments, a tool to help with finding test edits in articles.
  • Vada, an online cloud based framework.
  • AddBad, some thoughts on a new generation of recent changes patrol applications and a description of a prototype application based on those thoughts (2014–16, now inactive).
