Thanks for the comments. Yes, I think she was just trying her luck and attempting to scare me into taking my listings down. I used ChatGPT to help me write a response explaining that I haven’t copied her designs, so I won’t be taking down my listings. She replied saying that she would take it further with Etsy, but I haven’t heard anything since. After doing some research into the situation, I don’t think she would have a particularly strong case, so I’m not too worried at the moment.
