I posted about that myself.
I kept having people posting on my wall about some stupid zoo game.
Facebook scares the bleep out of me because I have been infected 2 or 3 times with malware that came from something on it.
I did some checking around and there are sooooo many ways to pass a virus or malware there, it's a joke that people don't talk about it more. Just by agreeing to be someones friend, the action that executes can be manipulated to infect you. Every single stupid application there can be manipulated to infect you.
I am basically only accessing it through my iPhone now, don't want to risk it anymore, after spending 2 days removing malware.
