At Polyvore, we take copyright issues very seriously. Our goal is to be a place where both Polyvore set creators and the owners of the items in those sets will benefit from the community. It's in everyone's best interest for these items to link back to where they were found. First, it gives the owner proper credit and hopefully drives traffic back to their site. Second, in many cases it allows anyone to discover and buy these products.
For example, these Etsy earrings are the perfect accessory for this outfit:
Someone wondering what to wear with a dress like this can find inspiration from a set such as this one, and they can click on the green Etsy link to purchase those earrings. In a perfect world, that's how Polyvore should work.
In the case of Etsy, some product images have been imported that do not link directly back to the shop. When this happens, it can obviously be very upsetting. This is mainly a technology issue that we're currently trying to solve (see Pasha's explanation here). The best we can do now is to respond to requests from individual copyright owners as soon as we receive them.
In some other cases, Etsy artwork has been used in a way that the owner dislikes. Polyvore members create collages that can be very artistic in their own right, but we will always respect the rights of the original artists. Many Etsy folks are fired up about this, and we understand. These images are copyrighted by their respective owners and they have the right to request that their images be removed from Polyvore at any time. Any Etsy shop-owner can write an email to "copyright at polyvore dot com", and have their items removed from Polyvore if they so choose.
That aside, you should also be aware that many Etsy folks are quite happy to have their products featured on Polyvore, and have already been using Polyvore to promote their products. In response to the recent Etsy uproar, we've blocked importing products from Etsy and some Etsy members have been complaining in response.
So, what can we do now? Well, as good citizens of Polyvore, please be sure to import images from the page where they can be purchased - never download Jpeg or Gif files to be imported into Polyvore. Doing so makes it difficult for us to know where the image came from. And to the Etsy folks: we're very sorry for the situation and any ill feelings it has caused. We will be running an Etsy promotion on Polyvore once these issues are solved. However, please, don't take it out on our members - just send us an email! Our success depends on the happiness of our community, and as such, we'll do everything in our power to accomodate your requests.
