Wikipedia:Vandalism_in_progress

This page is to report vandals, spammers, and usernames that violate the username policy, to administrators for blocking.

To better help administrators, please use the {vandal} template if the vandal has an account or the {ipvandal} template if it is an IP address.

• If a report has not been replied to in a reasonable amount of time, and an immediate response is required to prevent ongoing harm or vandalism to the project, ping administrators in the IRC #wikipedia-simple ^connect channel using !admin@simplewiki or in the Discord channel #simple-english-wikipedia using @SimpleEnglishAdmins

Examples:

• {vandal|Bad user} gives "Bad user (talk • contribs • CA • deleted contribs • nuke contribs • logs • filter log • block user • block log)"
• {ipvandal|192.0.2.16} gives "192.0.2.16 (talk · contribs · deleted contribs · filter log · WHOIS · RDNS · RBLs · http · block user · block log)"

Reporting bad usernames? Try using {subst:UsernameWarn} on their talk pages for those who just need a warning.
