Another good point is that since Yonkou of this site can't be defeated by non-yonkous, if there are more yonkous every few months, there would be less for others to defeat. I agree with the supernova's vote.

Of about every now or then, the site's yonkous would be replaced by new ones; therefore will eligible of being defeated but still have the honor of being yonkou before?
