It's sites like these that have made me wish I could downvote or mark-as-spam from the search results. Why can't I tell Google that I never want to see results from certain URLs ever again?
I would love to see this feature. Preferably as a way for search results to be "voted-down" by multiple users, with an aggregated score (this would probably be heavily gamed/spammed by black hat SEO people, and become useless anyway).
At the very least if I am logged into my gmail account, I should be able to hide certain site from being returned in my personal results.
