User blog comment:Meighan/Wiki Wisdom: Reacting to Trolls and Vandalism/@comment-2217546-20111113062516

I do warn a vandal of exactly what they did wrong, making sure to retain a sense of authority. Typically after issuing a warning I never hear back from the vandal. They never edit or comment proceeding the warning, with a few exceptions in which more than one warning has been issued. For me, this has never backfired.
