Given the current high-ranking thread about spammy sites in Google results, it strikes me that a very simple solution would be to let logged-in users blacklist sites.

Bam, no more wareseeker or efreedom.

This would solve a lot of people's complaints in one fell swoop.

There are greasemonkey etc. scripts to do this, but they're tied to a single browser on a single machine. A global filter (like in gmail) would be so much more useful.

Would this be particularly hard to do?
