Nostalrius Begins - Quality wow vanilla realm (1.12)

My account ID is fatpy, I did assignment with my team member in Dire Maul North on December 4. My team leader uses BUG arbitrarily without telling if use or not and I have no idea. On December 5, my friend and I had a transaction of 400 gold coins for buying rider. My friend’s ID is fatlx. I logged in the game on December 6 and found that my account was permanently blocked. Since I have no idea of this and passively violate the game rule and thus leads to permanent block of my ID, I hereby plead, GM please kindly deblock my ID. If it can be deblocked, please let return the 400 gold coins donated by my friend to him. My friend’s ID is fatlx.
Thanks a lot!
