How do they currently do it outside of Pinterest? They don't. Flickr makes an effort to spell out to visitors the terms of your image's copyright (whatever they may be), as a photographer that's where their responsibility ends, and I'm ok with that. I do not expect Flickr to slap DRM on it on my behalf and go out of its way to prevent the inevitable. If someone wants to throw my photos on imgur and share them without attribution, there's not a lick of anything I can do about it, Pinterest or otherwise. Flickr has done its due diligence informing users about the legalities of whatever use they have in mind, and that's fine. Also, when I hit the Pinterest bookmarklet, I am logged into Flickr, and staring at one of its own pages. Flickr knows exactly who I am - the same logic that's locking out Pinterest could just as well check if I have permissions to share these images.
