hacking facebook accounts needs social engineering , the only thing they could do is freezing your account for a while or trying to log in with crpg form password. or spamming your wall .
btw we are all doomed !!!!!
Well, IF they knew your email and IF they knew your c-rpg.net password and IF that was a common password you used in multiple locations, then it would be trivially easy to login to your facebook account.
This is, incidentally, why it's important to have multiple passwords. I do share some passwords but, for example, the only place that uses my c-rpg.net password is c-rpg.net. I use a different password for Amazon and Facebook and Gmail, etc. If you use the same password for everything you're really begging for trouble. One leak anywhere and it's all over for you.
