I selected this as it was something I have never heard of, but have been a victim of. A while a go I did a quiz on Facebook and ever since an app has been posting random results on my website, the last straw being when one of them compared me to George HW Bush. I looked at my apps and along with that one, there were over 16O I didn’t knowingly install, which I have since removed.
I found this video, which opened my eyes to how prevalent it is on Facebook and how I have unknowingly been allowing access to my data and that of my friends by my not being able to resist quizzes. I will definitely be changing my behaviour now and I have warned all my friends likewise. Clicker beware!
