I recently stumbled across [[Wikipedia:Requests_for_arbitration/HistoryBuffEr_and_Jayjg/Evidence/Full_version]], and ... wow! I've neither knowledge of this dispute nor any great ideas on how Wikipedia should do arbitration, but I think this 500k page is one of the most mind-boggling -- and disturbing -- artifacts I've yet come across on Wikipedia ;-)
(Sorry, I don't really have a point, I just needed to voice a "wow".)
I'm rather disturbed by it myself, ;-)
