I disagree. Pinterest would certainly qualify for safe harbor due to the "Automated upload mechanism". Meaning they have no manual or editorial review process. Users simply click and it happens through code. That's the biggest distinction.

Yep. I don't see how it's any different from someone uploading a copyrighted video to youtube...

Did you miss the part where users don't actually do the uploading? Just a minor point, but potentially important.

They're both essentially a single button click. Technically, there is a difference. Realistically, there isn't.

I personally know one company which lost a court case based on that defense. Not in US/under DMCA, though.
