Someone is using my photos on Pinterest
A Pinterest Pin is using your Etsy photos. Do these three things before you pay anyone who emails you offering to handle it.
Save the page. Copy the link to each Pin, take screenshots, and write down the date. Your original Etsy listing, and the files you uploaded, are the proof the photos are yours.
Report it on Pinterest's own form. You have to be the rights holder or someone they authorized. The form is pinterest.com/about/copyright/dmca-pin. It does not ask you to sign in first. Choose An image. Paste the link to each Pin, and point at your original Etsy listing. If you want every identical copy of that photo taken down, check Remove All. Pinterest says a resized or altered copy will not come down that way. Temu, SHEIN, Amazon, eBay, AliExpress, Walmart, TikTok Shop, Shopify stores, DHgate, and other Etsy shops have their own forms. Use those, not a random email.
If Etsy removed your listing because the copy showed up first, write Etsy and show them your original files and the date you published.
