- This guide only applies to vandalism as defined by official policy.
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 "Publish changes".
- See also the section below for tools to help with reverting.
2. Warn the vandal. Access the vandal's talk page and warn them using an appropriate template.
- See this overview of the most commonly used warning templates and this table for a wider selection of warning templates.
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).
