Blizzard has a large PR department. And a lot of loyal fans in their forums and on social media in general. Blizzard is not really able to process criticism of any kind, and also does not like fundamental criticism on their boards. To actually achieve the goal of moderating the contents of their boards, they use loyal trolls to get their agenda going. While they punish every rule violation in negative feedback with trolling and spamming infractions.
They do not infract or ban loyal trolls. Means, trolls which talk for blizzards agenda or sake. Means trolls which help blizzard to get rid of topics they do not like. These trolls know that, so they attack criticism with ad hominem posts and personal attacks up to insults.
I have seen that a lot on their game forums. And it always works in the same pattern. In special in the WoW forums they use this method, and generic reasons as like trolling and spamming to get rid of unwanted opinions.
Have you encountered this behaviour of blizzard on their game forums as well? Or have you always been treated fair?
