It's the anonymity of the internet that creates this, not just from allowing inexcusable behavior with no repercussions (as from greater internet fuckwad theory), but from the distrust of the source of the information. You don't know if a poster is a honest fan praising Killzone for its virtues, or a viral marketer for Sony trying to sway your opinion. We can't trust the source of opinions because we know nothing about their source, so our natural fear of the unknown causes us to assume the worst by default. That?s why sites like gametrailers can pan games without it being seen as fanboyism, because we know where they?re coming from and trust that they?re not pushing any agenda.
