There are always all kinds of comments with biting sarcasm in community forums. Of course, to Blizzard, there is no escape from fate. But, sometimes, they are just intense war of words regarding various ideas.
However, sometimes, there are some people giving sharp comments. Lylirra, gave the reply to this kind of players as follows,
Regardless of one's feelings about Diablo III and its development team, harassment directed at its employees is not permitted in these forums (especially when it comes to threats of violence). It is never appropriate to suggest real-life harm within this or any Blizzard community, and we will respond to such threats with all due diligence.
We welcome criticism provided that it is shared constructively; however, defamatory language that has a clear malicious intent and/or fails to promote positive discussion -- which you have been so kind to illustrate -- will not be tolerated, and in many cases will lead to a notable vacation of your posting privileges. Please take this time to reconsider how you communicate within this forum.
