I believe that Portal rigged the votes to make sure that Snick0rz wins, then when he wins Portal will claim that Snick0rz rigged the votes when it was really him. Hmmm..
No, it was much simpler.
Portal made sure Snick0rz wins, faking his anger with the results of the vote, also resulting in a rebellion to throw portal off the server, taking his administrative rights and banning him. Meanwhile, Portal assassinates Snick, takes his place in the server using his key, and reassures his place in the server as the one and only king.
