Well I dunno how they do it...
Yesterday I even commented harshly at a guy who in all apparences is a nintendo supporter (game collection) but somehow seemed to be just as biased in his comments on the 3DS.... Worst part is that even PS fans went at him for the comments on Vita, so he managed to antagonize both sides... This really means it's not the users that are biased in the comments (or it could mean that the guy is so unbiased that he sees the truth... but that was not the case).
