Use http://dukgo.com instead of its less quality-motivated big brothers. If google, et al. see duckduckgo usage spikes, they will likely implement similar filtration measures. Then they will post blog updates about how awesome they are for adding said measures to their service. And I will read about it after searching with duckduckgo.
I use duckduckgo as the default search engine with Chrome, and it works really nice. The key to make switching easy: Preface your query with, like `!g my-query' or `"!bing my-query' to search on Google or Bing. Useful, because for me Google is still better on searching stuff in German.
Just using `! my-query' gives you I'm-feeling-lucky semantics.
