If the recruiter password got into the wrong hands that could be the cause. Have any ex-staff had access to the recruiter account that may have been angered and shared the password with someone? This seems to be a matter that staff would need to look into... not much anyone else can do at this point.
I suggest creating a new account with an entirely new password for the character instead of using the one mentioned here. That would keep the exploiter out of it. I also recommend asking a staff member for further assistance on looking into this issue.
