It's definitely easy to set up. I'm thinking about making a greasemonkey script to put a button next to my search results and let me block the site if I hate it, rather than go do it manually as you suggested (which is easy but takes more time than hitting a button). Alternatively I will stick to my plan to change search providers. One way or another.
