Indeed, I had to switch back from DuckDuckGo to Google as I just couldn't deal with all the nonsense sites that polluted my search results, and DDG doesn't offer a personal blocklist feature to eliminate them. For example, sites like yellowpages.com, whitepages.com, superpages.com, zillow.com, citysquares.com will all pollute basic searches that look like job descriptions ("custom cabinetry new york", for example). (I complained to DDG about this a while back, and it looks like they have added some negative boosts to some spam sites.)
