I got hacked 3 times in my gaminglife now, and even without going on such sites, phishing, giving my password to other people or many other things.
My password was just one little word.
But I have my current account for a very long time now, and I didn't get hacked for now, my password is now a long word plus random numbers, but I think a good hacker can even hack this one.
So maybe you got hacked by a random guy or something. :/
