Facebook is evil. Every now and then I would see posts of some celebrity that died and it wasn't even true. News stories that are still going around when it was first posted in 2011.
And those quizzes you talked about, I did one just to see a few weeks ago. It posted the results on facebook without even asking me the permission to put it there. Just popped in there. I gave everyone warning that I wasn't the one to post it and for people to be careful. People still do it. They are facebook zombies and are not waking up.
