i played asia region, and see something like anti cheat... QQ726.... i dont know what the situation is on BFV currently, i just know how correctly i enter something, it will disappear and the above sentense is keeping refresh . i dont think EA server have a server on QQ that are product similar with gmail or goolge in china. if it is abnormal , pls take a look on it in asia region, chat window as i didnt know about any change or somethign currently in BFV as i didnt play it long time ago..
