Pinterest does work hard to ensure that proper accreditation with link is included in every image and if that's not there they will act on a complaint, if you make one.
I don't care for accreditation and Pinterest's fail nofollow links; I want and need visitors to make my website a worthwhile enterprise, as it should be under protection of current copyright laws.
The attribution and link actually drive traffic as well so there is a benefit.
That may only be true for Martha Stewart and recipe websites. For mine, Pinterest has represented a traffic loss of ~10%. This spring I had about 5000 instances of infringement. My traffic was down from the previous 3 yr average by 10%. From these 5000 instances of infringement, I would receive fewer than 50 referrals per month. That's right; per month.
I spend two months this summer, full-time, weekdays and weekends, sending Pinterest DMCA take downs.
Incredibly, my traffic, that usually falls in summer, was actually rising as I was removing the content.
Pinterest caused me to compete against my own content, as displayed on their pages - and in doing so, appears to have been stealing my traffic.
It's not a good thing when the prevailing culture is "everyone-infringes-huzzah" and "let-the-content-owners-chase-their-content" until they do nothing but chase their content in order to keep on publishing.
My traffic is much better since I have cleansed Pinterest of my content.
