One World of Warcraft player, Jim Brand, contacted BBC News to say how disappointed he was over the change.
"I have been using the forums for over five years, reporting bugs and trying to be helpful. Now, to have the privilege to help people on the forums I have to reveal my real name; I'm dead against it," he said.
"I work in a charity and deal with governments officials. If they do a search and see I am a gamer, it could affect my employment prospects," he added.
It will now, Jim. Well done.
