Thanks this seems to be the closest. On the search results page the Pinterest results still appear, but without a link to the site, so you see floating paragraphs. On the image results page the pinterest results do seem to disappear.

I tried setting the upward() to 2, but that got rid of all the image results.

Thank-you so much! It's been a disease on my browser for too long

Excellent, thanks. I am so glad to have that pinterest shit out of my search results. Companies that try to take over your life, even in small ways, should all fall apart.
