A while ago I got fed up with continuously finding w3schools in my search results when I wanted detailed, technically correct information.
To fix this without having to continuously append -site:w3schools.com to my search queries, I used Google's Manage Blocked Sites page.
For a while this worked perfectly, no more results from unwanted sites. Recently, however, I've been seeing w3schools litter my search results.
Is there a new way to remove a site from Google search results?
-or-
Is this just a bug that I should report?

The only solution you have for now is a browser script/extension.
