There is a change on Pinterest on how pins taken from search engine results are identified. Whereas only the result page URL was recorded before, now, the image links still leads to the result page, but Pinterest has added a link to the original source.
As usual, Pinterest is the master of half-arsed measures. Why is Pinterest accepting pins from search engines images at all? And if they are accepting such pins, and recording the original source, why are they not respecting their own proprietary nopin metatag?
That's right; the bozos handling the programming aren't respecting the nopin metatag when users pin from search engine image results.
Adding insult to injury, the new link to the source is given a "nofollow" attribute, rendering it useless to the content creator.
