Ignore does not work when they delete the toon and setup another to harass.
I cannot find a mod that ignores a trolls entire account but when I do or I write my own I will try to share it with the rest of the WoW gamers.
If you are on Shu'halo the list of Trolls you can add to your ignore list is right here on the forum. Many of the ignorant responses to the posts show the majority of the losers that are ruining this game for us gamers. I count around a dozen that really should be banned permanently - the rest are kids feeding off the tripe.
I do care when my character is attacked or my guild is constantly ripped on in trade. I spent a huge amount of time growing it since 1/2/2012 at the end of an expansion. I have come up with unique ways to make it fun to level or chase pixellated items while with our guild. The constant attacks are because of its success at allowing experienced and new players a place to play away from the haters and trolls.
Anyone that chooses to say something horribly inappropriate obviously to pass the child filters is and always will be labeled a Troll and Hater in my book. If WoW can't see that and chooses to ignore the facts it will continue to experience a decline in WoW subscriptions.
I ask you -Why accept it?- tell the Trolls and Haters to leave the game. I know I am and will continue to do so until I no longer desire to play. O.0
