With all the talk of Pinterest acting as one giant copyright infringement hub, the up-and-already-arrived social network has given sites a way to opt out of pinning. Though a Wall Street Journal article last week described that copyright infringements "haven't been a significant issue so far," Pinterest has taken the safe route, providing some code for websites that would rather their content not show up on the social network. This adds a technical aspect to the company's theft policy, which encourages citing original sources:
Pins are the most useful when they have links back to the original source. If you notice that a pin is not sourced correctly, leave a comment so the original pinner can update the source. Finding the original source is always preferable to a secondary source such as Google Image Search or a blog entry.
