I think everyone on the planet has taken a Facebook quiz. However Pacific Northwest National Laboratory is warning people NOT to do it here's why:
Cyber security experts at PNNL say you could be giving hackers ALL your personal information by taking quizzes. Penney Mckenzie an intern at PNNL says:

More and more often we come across suspicious surveys on social media. Typically it’s a survey with a couple of questions that claim to help you find out “What mythical creature are you?” or “Who loves you this month?” Not only do you fill in the information, but you tag your friends in the link so they can fill it out too. If you are not careful, you could give out valuable information for someone to use against you.

She even created a video to demonstrate the danger of Facebook Quizzes!
