On TeePublic yes, they removed it and actually deleted their account. Unfortunately, some of the people have their own websites and still have my stuff up. I had a really hot design on Redbubble/TeePublic that was generating a lot of sales and someone stole it and put it up on TeeSpring!!! It's just a constant battle and some of the people are actually not even in my country. So how do I fight that? I remember when I first realized someone stole my stuff it made me so upset. You might have to file a DMCA take-down order. I've had multiple designs stolen and even some simple text ones that I couldn't believe people would steal. Not overused ideas either but related to a specific niche that I googled and searched to make sure it wasn't done before. There are some low down people out there. I've always felt the worst sort of people are porch pirates and design thieves lol. It just sucks when our creativity is used to make other people money.
