This behavior is never going to change in regards to this game or any other, no matter how many voices implore the player base not to act this way. We can't control the attitudes of those that act out like knuckleheads hiding behind the anonymity behind a computer screen/tv towards other. Unfortunately, duty finder is a breeding grounds for these actions. As much as a well thought out tool to get content done, I still consider it one of the most anti-social ways to interact with other mmo players.
