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