Bug -hacker add a trial account to hack again

my english is not good ,i have posted it some days ago ,but this bug has not been repaired . if u keep "select account box" on ,u can login game again,the select box login time is unlimit,

Now all World of Warcraft accounts are associated with this email battle account, if your battle acount associated more than two World of Warcraft acounts ,when u login into game ,will display a box that need u select which account u need to login ,After a hacker hack your account and clean your gold and items , he will logout and then he can login into your battle account again and keep on "select account box " -----not into game ,keep on "select account box"
when u find your account has been hacked ,u will recover your new password and report it to gamemaster,then he will recover you lost gold and items ...Ha ha two days later,when u recover your gold and items ,the hacker can login into game with" keep on select account box" Whether u changed your password ,hacker also can login your account ,because the box login time is unlimit
Someone have only one account associated with battle account ,hacker will add a trial account , your account will become two wow account too ,so he can keep on "select account box" and hack your account again
