To be fair, Flickr has implemented the ability to opt out of "pinning" via a setting: http://www.flickr.com/account/prefs/sharing?from=privacy This adds the "nopin" meta tag to your pages automatically.

However, to be even more fair, the burden was on Flickr to implement this, not Pinterest. Pinterest is still encouraging copyright violation.

Exactly, the onus should be upon Pinterest not Flickr.
