winterhawk11, you can also take quizzes without posting your results. Every quiz I’ve taken has had publishing results as a separate, optional step.
You can also change your settings so you don’t get bombarded with advertisements that use your friend’s names. E.g, “Bob score 134 in an IQ test, click here to beat Bob’s score” when Bob didn’t even take an IQ test and his name has just been trawled from your friends list.
I do this every few months. My upper limit is somewhere around 40. If I don’t interact with somebody at least once in a while, in some way or another, then I really don’t need to have them as a friend on FB.
Wow. You should have deleted them, not yourself.
