Hacked - When an unauthorized programmer gains access into a secure network or Web site, usually by breaking security systems or using a stolen login and password.
I would just like to say that anyone who claims they were "Hacked" deserves a big slap across the face.
In the past there were some issues with the server being insecure, but to my knowledge thats been fixed. I see so many cases of people claiming they were "Hacked". Im quite sick of seeing people claim this, when if you did infact lose your account - it was mostlikely your own fault.
Downloading Bots/"Hacks"/whatever related to sro from a random site will generally land your account in the hands of someone else. (Keyloggers/trojans/etc)
Giving out your login to someone will land your account in someone else's hands. (I know this is obvious, but this is a huge reason why people claim they were hacked...)
Having a password that is easy to crack (Bruteforce) This is the most common way that people are currently using to "Hack" your accounts. Using a program/script designed to use all possible passwords, just spamming the server with attempts to get in. (obviously this can take quite some time, and if your password is secure enough will never happen)
So be sure you have numbers, letters, Capslock, in your password, if your password was just numbers, or just letters... its much easier to get in to.
