Well.. They would have to implement such technology, if they are to survive.

But right now there are some huge threats to Pinterest existence, both in copyright issues and the fact that they are being attacked by every marketer in the world wanting their user eye-balls. In the end maybe chasing those same users away. Killing the fad.

Personally I am not sure that the rather significant investor list, will keep funding a site that is a known theft tool and whose value is being diluted with thousands of fake Pin-boards and new marketeers.

Their investor list per their site including Jack Abraham (Milo), Michael Birch (Bebo), Scott Belsky (Behance), Shana Fisher (Highline Venture Partners), Ron Conway (SV Angel), Kevin Hartz (EventBrite), Jeremy Stoppelman (Yelp), Hank Vigil, Fritz Lanman, and Brian S. Cohen

Some of them I have a hard time seeing investing too much in that kind of bad publicity.
