Unfortunately, as much as I'd like to just ban them, I've totally gotten answers to questions from there before (at first using Google cache, until someone showed me the now-stupidly-obvious-in-retrospect scroll-down-to-the-bottom technique), so I know banning them from my listings will make my life slightly worse, and I can always ignore them.
Which, I guess, is a mindset that I think generally makes this concept not terribly useful: you can always personally ignore some domains that suck. The real issue is how many places have duplicate content, or even stupidly "reblogged"/"syndicated" content, that show up when you search for something: the domains for that are often very search-specific.
