Anyone unconvinced that Wikipedia is run on a "some animals are more equal than others" basis should look at MONGO's ongoing efforts to pin something on SevenOfDiamonds, as seen in its latest stage here:
http://en.wikipedia.org/wiki/Wikipedia:Administrators%27_noticeboard/A rbitration_enforcement
Having tried and failed multiple times to get SevenOfDiamonds labeled as one or another of various banned users of the past, he had yet another try here, still failing to prove his point even though he had the support and sympathy of various admins.
The great irony in all of this is that MONGO and his friends love to attack and ridicule everybody who keeps trying to bring actions against MONGO; the fact that almost all of them have failed (except for the one that led to his desysopping) is given as evidence that they're all frivolous and laughable, and that the people who bring them should be sanctioned for harassment.
By those standards, MONGO is certainly guilty of harrassment for his repeated unsuccessful attempts to bring action against this user.
