They seem to have gone to a lot of trouble to insert themselves between the site users visited intentionally to find what they were looking for (Google), and the site that actually provided what they were looking for.
They've essentially become a large MITM attack on Google Image results.
Edit: just tried a few arbitrary search strings on Google Images, it seems improved compared to the past few weeks/months, somewhat.
For some searches, Pinterest results didn't appear at all. For "esp8266 enclosure", only 1 out of 15 on the "front page" points to Pinterest, but the original image is still from Tindie, not Pinterest. The person who supposedly pinned that image describes themselves as "Creative Digital Marketing, Web designer, WebDev, crazy SEO".
Ok, maybe a real pin from a real person, maybe.
Then I decided to see what happens with a handful of more "NSFW" search terms. The number of Pinterest results varied but significantly increased overall.
For some terms, in the 3 rows of images visible without scrolling, there were 19 images, and 11 of them (57%) pointed to Pinterest. None of them were images originally posted on Pinterest, they all have a hover link to the original site.
However, even though Pinterest is providing a link to the original site on top of the image, clicking it doesn't always take you there.
A good bit of the time, Pinterest has chosen to redirect you to a "blocked site" page instead, and only after they have already displayed an image from a site that they deemed "inappropriate". And then shortly afterward a giant popup prompting the user to login or create an account filled the screen.

Search for things like "Acorn Tattoo", and similar terms and you find pinterest spam is all there is in the google image search results.
Their behavior is eerily reminiscent of expertsexchange, back in the day. They had a similar high ranking for lots of things, but the result-pages were all horrid and non-useful to actual visitors.
Happily stackexchange surpassed expertsexchange, and I hope that something comes to kick pinterest from its niche too - one of only two sites I wish to fail (the other being linkedin, for similar evil reasons).
Replying to myself after doing some additional testing.
I've now seen multiple examples of Pinterest hosting images with the "original link" being a Google Images search result page, complete with the huge URL query string intact.
While it's possible users who don't know how to find the original URL for an image are pinning Google Image pages instead, the accounts that have pinned them do not look like real people.
It really makes it look like Pinterest is crawling Google Images for specific search terms, auto-generating pages to match the results, and then manipulating Google to get their own pages to show up in Google instead.
