I think I may have figured out how you can avoid seeing those faces staring at you, all the time When I go to Facebook, I notice that those profiles are never present -- and I think it has to do with how I bookmarked the site -- I just see Facebook.com in the browser. I'm on the home page, but I still see all my friends updates. It's only when I click on my name at the top and go to my timeline of the page that I'm seeing "People You May Know."
So...just bookmark the Facebook home page, log in, and you can avoid all those bloody images coming at you. Try that and let me know if that works for you.
