Wikipedia:Cleaning up vandalism

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

1. Revert the vandalism by viewing the page's history and 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 "Save page".

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

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

Some useful reminders:

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

The old school way is to load 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 (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:

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

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