Nostalrius Begins - Quality wow vanilla realm (1.12)

How do you expect to protect your users when you don't give a warning on the login screen or the greeting message with a link to where to change the password or a little heads up that there was a huge hack? I had to look on reddit to find out why my bags and gold were empty

There was no hack. You either used the same login details on another private server, have a keylogger not doing malware scans on a regular basis, or shared your account info and your 'bro' pranked you.
