I think Hellspawnxxx xplains it well on the MMO champion Forums as he typed back in may.. So im just going to quote what he said.
So has ANET said wether or not Dhuum will be in GW2 as in the Epic ban Hammer ANET wields. I loved watching Dhuum raise from the ground and scything a player into oblivion, Banning them from the game.
I think the reasons Guildwars 1 community was so strong and mature, is because ANET had almost zero tolerance for Botters, Hackers and Abusive Players. That kind of goes hand in hand with a none monthly sub MMO.
In some other MMO which I wont name but I will say I enjoyed playing for over 6 yrs in that particular MMO you seen alot of immature abusive behavior from players towards the community. Trade chat was riddled with racial slurs amd extreme profanity because the players being detremental too others knew that the game wouldnt Ban them. When your paying someone $15.00 a month they are inclined to look the other way in most situations that ANET would just perma ban you for.
The lesson of the story is once you buy GW2 ANET has your money so dont be abusive or exploitive because they will drop the Epic Dhuum Ban Hammer on you assuming Dhuum is also in GW2.
For those of you who are not aware of being Dhuum’d is. Its when ANET spawns a NPC to kill you named Dhuum and once you die your banned. Its very funny to watch heres a video enjoy…
