if my usual searches include "milf giant milk juggs" should i be worried?

DuckDuckGo goes into more details in their privacy policy. But I'm not sure this is accessible to the average web user. Worth a look.

Reminds me of Scroogle. (web service that allowed users to perform Google searches without user info being kept).

Its not a big deal, but why would anyone hate them? They always tend to get shut down.

Scroogle began to have problems with Google throttling, being periodically blocked for 90 minute intervals. Google denied targeting Scroogle, saying the site may have been triggering automated anti-spam mechanisms.[5] In February 2012, Scroogle was shut down by its creator.[17] Brandt blamed a DDoS attack by someone with "a personal vendetta" combined with throttling by Google for the site's demise.[17] Brandt's other sites - NameBase.org, Google-watch.org, CIA-on-campus.org, and book-grab.com - were also taken offline at the same time.
