New and useful for picture researchers of various types, a UserScript to “Hide pinterest.com in Google Images” search results. Uses a simple ‘if result contains pinterest.com, do not display’ CSS method. The script is easy to tweak and as such it could be adapted for other image sites that you find are verbose/useless (e.g. Alamy and its ilk), without the need for a full-blown URL blocker add-on.

Why kill Pinterest? Because it poisons search-engines. 70% of the time you can never actually get to the image shown in the results.
