Look at the history for [[Wikipedia:Requests for arbitration/KaintheScion et al./Proposed decision]]

Enviroknot (aka, Kain the Scion) didn't like the decision we had in progress, so he decided to vandalize the decision page by hopping TOR proxies: http://en.wikipedia.org/w/index.php?title=Wikipedia:Requests_for_arbitration...

While this was a relatively backwoods out-of-the-way page, it could very well have been any article or articles.
