There's been quite a number of people getting hacked as of recent.
People are getting hacked as a result of using the same passwords on other private servers/websites. I would advise every player to make sure they're using a password they've never used before, as well as putting your account security to HIGH.
In order to do this, go to the settings tab and put it on medium by clicking the low setting. Then open up your bank interface and click on the bottom middle of the interface to set a bank pin. This pin will be required only once, upon every login on your account. (The bankpin is required for the HIGH setting)
