It has come to my attention that numerous AC members have been getting hacked or have had their account locked due to another unknown person on their account.
There are many ways to secure your account to best of your abilities:
1) Having a complicated password
2) Having a bank PIN
3) Enabling the JaGex Authenticator
4) Regularly scanning your computer to check for threats.
Its 2015, you shouldn't be getting hacked..
