Nearly every day I find numerous instances of my copyrighted photos "pinned" on Pinterest without permission. One photo had been "repinned" 43 times! Even worse, numerous images that have nothing to do with me are erroneously listed under my blog's domain name. And a British company hijacked my photograph found on Pinterest - therefore in their perception, free - for an advertising/promotional campaign.
I installed the "do not pin" code on my website and deleted my 500px and Tumblr accounts because I couldn't stop photo theft. And in a series of conversations, I've asked Pinterest to block all incoming images linked to my domain names and do a better job informing its users of copyright issues. At the top of my blog's sidebar I specifically request that my photos not be copied or "pinned." I've written several blog posts about why I do not want even a single photo on Pinterest, a site for which I receive no benefit whatsoever. Yet still this problem persists. Am I going to have to plaster every photo with "Do not pin" and/or a copyright notice??!!
Not that you'd notice with all the annoying "Do not pin" reminders, but this is a photo of a 19th-century door with a copper Arts & Crafts letterplate in Sevilla, Spain.
