Pinterest gained popularity without Google. If it's true that Pinterest ranks well then it is ranking well because of link equity and other metrics of popularity. Furthermore, Pinterest has a value-add. It's not just the scraped content, it's the community. Just to make sure it's clear: Pinterest has a value-add, several actually, but perhaps the most important value-add is community.
I'm not defending Pinterest or trying to justify it's place in the SERPs. I'm simply pointing out the flaw in the premise underlying this discussion. Pinterest has a value-add, push-button scraper sites do not.
Think about movie trailer sites. Many if not most of the sites that rank for movie trailers have value-adds. The content, movie trailers, are pretty much exactly the same. The differentiator comes in the value-add.
Pinterst got to where it is through marketing and the popularity of it's community. Scrapers do not offer community or any other value add. Huge difference between the two.
Pinterst is not in the same class as pushbutton scraper sites. Anyone who chooses to view Pinterest in those terms is willfully closing their eyes not just to the truth/reality but to an opportunity of learning something about successfully marketing a website.
