How to get rid of my friends quiz results on Facebook?

The simplest thing is to look for the itty bitty triangle near the top of their post on your wall. You can click it and one of the options will be "Block 'What Star Trek Character Are You?'". And then, at least, you won't see any more results from anybody on those quizzes. The problem with this approach is that you end up having to block every quiz, one by one.

Another thing you can do is follow some of the privacy settings on this web page:

While you're not so interested in keeping your information private, some of the techniques (grouping your friends and setting different permissions for the groups) will pay off. You'll see more updates from the close friends and fewer updates from the distant acquaintances.
