My Facebook account has been hacked some time ago. I did not really notice it at first since I do not access my Facebook account every single day, but when I noticed it, it was already almost too late to do anything about it. I was lucky that I was able to recover my password and that everything turned out to be good in the end. Having said that, I am aware that not everybody is as fortunate as I am. Every day, thousands of Facebook accounts are being compromised and their owners know very little how to prevent those hacks from happening.
