Hello and thank you for recently undoing unconstructive edits. In the future, when you undo unconstructive edits, could you please use the appropriate template to warn the user (IP or registered) to stop their behaviour?

There are many different warning templates available to use. Here are some common ones; please see their documentation pages for instructions:

• {{subst:uw-test1}} – For the first case of what appears to be a test edit
• {{subst:uw-subtle1}} – For the first case of editing in a manner that is difficult to distinguish from vandalism
• {{subst:uw-disruptive1}} – For the first case of disruptive editing
• {{subst:uw-vandalism1}} – For the first case of clear vandalism

Each time we use these warnings they should be placed under the title "==June 2026==" (updated to the current month and year), on the user's talk page. Beyond those listed above, there are also higher level warnings for continued unconstructive editing (see the template documentation for details); if previous warnings have been given under that title, add the next level warning beneath the others, within that section. Individual cases must be dealt with as seems appropriate. If the user has not been actively unconstructively editing for a few weeks or months, start a new section. It may sometimes be appropriate to cut to the chase and use:

• {{subst:Uw-vandalism4im}} – Last or only warning

The value of warning is three-fold:

• Firstly – it may be heeded
• Secondly – it allows other editors to quickly see if that user has been vandalizing frequently or recently
• Lastly – administrators require that warnings have been given before they can or will act against persistent vandals

If a vandal is on a spree or has reached a level 4 vandalism warning and is currently active, waste no time in reporting them to Wikipedia:Administrator intervention against vandalism.

Thanks again for helping to protect articles on Wikipedia. Happy editing! 🙂 ~~~~
