User:Lupin/Anti-vandal tool

From Wikipedia, the free encyclopedia
Action using Mozilla Firefox.

Lupin's Anti-Vandal Tool is a utility that detects and uncovers instances of wiki-targeted online vandalism. By using the RC feed to check a wiki-page's differences against a list of common vandal terms, this tool will detect many of the commonly known acts of online vandalism.


Copy the following content into your common.js file. After it is saved, press CTRL+F5 (FN+F5 for Mac OSX) to reload the common.js file.


Save the page and follow the instructions above the edit window to force-reload the page and clear your browser cache.

If you want to use the script on another wiki, you can find the code to use in your monobook.js file by first using the above instructions on this wiki, then copying and adapting the resulting code. You'll also have to copy and adapt the script for your wiki.


There should now be five new items in your toolbox (just under the Search bar of monobook skin):

When you visit these pages, a live, scrolling feed will begin. When filtering recent changes, only edits matching common vandalisms are listed (you can see this list at User:Lupin/badwords). If you select "All recent changes" then (nearly) every edit is listed, and if you click "Recent IP edits" then only edits by so-called anonymous IP editors are listed. "Monitor my watchlist" shows changes to your watched articles as they happen. "Live spellcheck" filters recent edits with spelling errors.

To check the contents of the entry, click on "show details". To hide that entry, click "hide details".


By default, all links created by the tool open in new windows (except the show/hide details links). If you want them to open in new tabs instead, the procedure for Firefox 2 is as follows:

  1. Select Tools → Options...
  2. If necessary, select the Tabs icon at the top of the Options dialog box.
  3. Under "New pages should be opened in", select "a new tab".

In Firefox 1.5, the procedure is as follows:

  1. Select Tools → Options...
  2. If necessary, select the Tabs icon at the top of the Options dialog box.
  3. Check "Force links that open new windows to open in:"
  4. Select "a new tab"

The following is the procedure for Firefox versions older than version 1.5:

  1. Type about:config in the location bar, filter for showsingle and set browser.tabs.showSingleWindowModePrefs to true
  2. Edit Firefox's preferences in Advanced → Tabbed Browsing and force links that open in new windows to open in new tabs.

Note: This option is hidden by default in older versions because it may not be completely stable.

Bugs and limitations[edit]

Wikipedia's RSS feed may have holes, although thanks to Tim Starling it should now have reasonable coverage. However, this tool will only examine edits sampled from that feed every 30 seconds, so it may miss some edits.



This tool has been tested with Mozilla Firefox and Opera, and has had limited testing with Internet Explorer, Google Chrome and Konqueror.

Note: The "Filter recent changes" option is not compatible with Firefox 4 and above, due to a new RegEx engine used by Firefox.
Note: Safari is currently incompatible on these fronts:
  • All AVT tracking currently suffers from a bug with the LEFTWARDS ARROW character breaking the visual presentation of the lists. This issue is tracked is bug 10370 and a fix will be available in Safari 3.1
  • Filter recent changes does not work because the RegExp on User:Lupin/badwords is too large for Safari to handle. bug 14873. However Safari 4.0.5 can open this list.

Wikipedia skins[edit]

A "Filter recent changes" link will only appear in the monobook and vector skins. However, you can visit the page User:Lupin/Filter recent changes in any skin and the tool should work.


You can add one (or all) of the following userboxes to your page, or, simply add this category to your userpage: [[Category:Wikipedians who use Anti-vandal tool|{{PAGENAME}}]]
