I just found so many of my designs that people have stolen and put in their stores. I am in the middle of reporting all the designs that have been stolen from me. I advise everyone to search and see if any of your designs have been stolen and report the thieves.
I have done these designs from scratch; I have all my Illustrator and Photoshop files, photography, etc. for my designs, so I am ready to battle if needed.
I’m really sorry about your situation! It’s very unpleasant, and sometimes I even hesitate to post here… On one occasion, they copied my design, including a typo I had made… It was quick, and they deleted it. Report it, because it’s one thing to get inspired by something you see and give it your own style, and another to copy it literally. Stay strong!
