I hate it... it scrapes lots of sites (in a 'nice' way from a legal point of view, as you need to view the original page rather than seeing it all there), and is basically a long-winded way of getting where you want to go.

To stop it, we all need to avoid clicking on their pages in search results (as the search engine keeps track, and increases their ranking each time).

Depending on the search engine you are using, you can eliminate their site by adding this to the end of your search text: -BigResource
(and if you use the search box built in to the browser, you may be able to add that permanently [how depends on the browser])
