My World of Warcraft account has been locked

As a Chinese Warcraft player, I am already very frustrated without a national server. In the past week, at the call of a friend, I entered Yafu and began to re-enter Azeroth, enjoying the game time happily. I was surprised to find that the Battle Network account was closed today. I swear that I have never used third-party scripts or illegal plugins. I hope the administrator can review it again and believe that there will be a fair review result.
