Forbidden nickname

In the begining I used non-english client and created my first character here. Now I use english client and I tried to create new character on Icecrown with the same nickname, but i cant, because in english client this nickname is forbidden.
I googled and found that this nickname is forbidden as it is associated with the drug. Now I'm afraid that I may be banned. What should I do ?

You will not get banned for this, but you will be forced to change your character name. If you send me a private message with your character name, we can solve this issue right away.
