Yes they block client side (several posts from matt confirm it in this thread). But you mention something important; for me I don't want to 100% block most of those websites, but to give them lower priority (never in my top 10 for exemple). Like you, as much as I hate Experts exchange sometimes they do have the answer when no one else does. This extension sems to solve that by giving a "show" link to display hidden results (when there are any).
