Cleaning Up Vandalism

This page offers an introduction tocleaning upvandalismon Wikipedia. For theWikiProjecton vandalism cleanup, see theCounter-Vandalism Unit.

A few things for current and aspiring vandal-fighters to keep in mind:

• Good-faith efforts to improve the encyclopedia are not vandalism, even if they are misguided or ill-considered.
• Content disputes are not vandalism. They should be dealt with by following thedispute resolutionprocedure.
• Most edits by new or unregistered contributors are NOT vandalism. Check out the content added or removed. Don't revert blindly, and remembernot to bite the newcomers.
• Edits that appear to be in bad faith should not be considered vandalism until they can be proven such at a later time.
• Learn about whatmotivates a vandal.

How to help

• Anyone can help! Whenever you spot a page that has been vandalised, you are encouraged to edit it and clean it up, and/or warn the vandal using an appropriate warning template. SeeWhat to do if you spot vandalismbelow.
• If you find yourself cleaning up vandalism frequently, you might be interested inpatrolling recent changes.Note that participation is entirely voluntary. Also,you are not required to enlistanywhere.
• There are various tools to help you. See theToolssection below.

What to do if you spot vandalism

This guide only applies tovandalismas defined byofficial policy.

1.Revertthe vandalism by viewing the page'shistoryand selecting the most recent version of the page prior to the vandalism. Use an edit summary such as 'rvv' or 'reverted vandalism' and click on the button "Publish changes".

See also the section below for tools to help with reverting.

2. Warnthe vandal. Access the vandal's talk page and warn them using an appropriate template.

Seethis overviewof the most commonly used warning templates andthis tablefor a wider selection of warning templates.

3. Reportvandals who continue to vandalise after having received a final warning. Most cases of vandalism should be reported toWP:AIV.Cases that are not simple vandalism can be reported toWP:AN/I.WP:LTAmay be used for reporting particular vandals who persistently return (e.g. viasockpuppets).

Keep in mind...

Some useful reminders:

• Civilityis one of the pillars of Wikipedia.Avoid being rude, no matter how aggressive or obnoxious the vandal is. Some of them may want you to become angry and lose your temper:Don't fall for that!
• Don't bite the newcomers.Not all bad edits are necessarily intentional vandalism. Some of them may just be test edits by newer editors.
• On manyISPs,IP addresses are shared by many users, so be extra-careful not to be rude in your messages, as people seeing them may not be the same ones who vandalised.
• Content disputes are not vandalism:If a user is adding biased content or you disagree with the information added, that doesn't mean the editor is vandalising. This includes violations ofWikipedia's Neutral Point of View policy.Corollary:3RR rulestill applies since it's not blatant vandalism. Instead of constantly reverting, discuss edits on talk pages and obtain community consensus. Seeresolving disputes.

Tools

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

Monitoring

Screenshot of Wikipedia recent changes IRC feed

Theold schoolway is to loadrecent changesand check the (diff) links. It can be filtered according tofeatured articles,good articles,living people,new accounts' contribs, IPs' contribs, mobile contribs (as these are more prone to vandalism, seeHelp:Recent changes), and even by likelihood of being damaging or bad-faith. Searching for pages by theirnamespaceand specifictags(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:

• Huggleis 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 therollbackpermission to use it; however, this is not a requirement on other wikis.
• IRC Botsreport at the#cvn-wp-en^connectchannel on theLibera Chatnetwork list suspected vandalism edits (for example: blankings, edits made by blacklisted users, etc.).
• Lupin's Anti-Vandal Toolmonitors the RSS feed and flags edits with common vandalism terms. It also has a live spellcheck feature.
• RCMapgeolocates 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.

  Please be aware that this program is not hosted on Wikimedia Foundation servers

• RC Patrolis a lightweight script that makes it easier to patrol recent changes. After installing, visitthis 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 withHuggle.
• RedWarnpatrolcan be activated by any user of RedWarn on therecent changespage, quick reviewing and one-click rollback of disruptive edits.
• SWViewer(direct link) is a user-friendlywebappwith 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.
• AntiVandalis another web-based vandalism monitoring tool, similar to Huggle in User Interface. It can be used to quickly revert vandalism and warn the vandal using escalating or 4im only warning templates. Users can also directly report vandals toAdministrator Intervention against Vandalismafter sufficient warning has been given. Rollback or admin permission is required to use the script.
• WatchlistBotis anXMPPbot 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.

Rollback tools

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

• Huggle
• RedWarn
• SWViewer
• Ultraviolet
• AntiVandal
• User:Gracenotes/rollback.js
• User:Ilmari Karonen/rollbacksummary.js
• User:Writ_Keeper/rollbackSummary.js
• User:Plantaest/TwinkleMobile(using Twinkle on mobile)

Rollback-like scripts

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

• RC patrol scriptgives non-administrators revert, filter, and popup tools while using the monobook skin.
• RC review script for today's featured articlegives all editors access to see recent changes in thefeatured articleappearing on theMain page

  Please be aware that this program is not hosted on Wikimedia Foundation servers

• Navigation popupsare a set of utilities that appear when hovering over wikilinks. Particularly, hovering over links of old versions provides a "revert" link.
• Twinklegives 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 administratorsnearly twentytypes of rollback functions, including a "rollback preview" and "quick rollback".
• Ultravioletalso provides several different types of rollback functions for both non-administrators and administrators, like RedWarn.
• mobileUndo(new version) a script which allows you to revert when using the mobile interface.

Special pages

• User:Adam1213/warnis a page that simplifies the process of warning vandals by allowing warnings to be submitted to specific users directly from the page.

Task Forces

• Wikipedia:Counter-Vandalism UnitA voluntary group who will provide assistance at times of high levels of vandalism and advice on counter vandalism methods.
• Wikipedia:Recent changes patrolAnother voluntary group who will checkrecent changesfor recently edited pages and intervene if necessary.

IRC channels

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

• #cvn-wp-en^connectPrimaryRCbot listing (Activity feed only, discussion takes place in#wikipedia-en^connect)

  For a list of bot commands, seeCVNBot Documentation.To use these commands, you must have aNickServregistration, andbe voicedby a channel operator.

• #wikimedia-unifications^connectAccount creations
• #cvn-commons-uploads^connectFile uploads
• #cvn-wp-en-cluenet^connectChannel that reroutes information from ClueNet. (Read-only, only staff and bots can speak)

Vandalism Detection Score Services

• WMF ORESis a web service and API that providesmachine learningas a servicefor Wikimedia projects maintained by theScoring 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.”

Other

• 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 from5to1and/or add a short comment;5indicates very low levels of vandalism, and1indicates extremely high. You can add the vandalism information template to your userpage to stay up to date. SeeTemplate talk:Vandalism informationfor different styles.
• Countervandalism Network,volunteer group that operates the "#cvn-" channels. This group is not owned by or affiliated with Wikimedia Foundation.
• Wikilink scriptsenable 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 atWikiProject User scripts/Scripts(WP:JS)
• Template:Toolbar experiments,a tool to help with finding test edits in articles.
