So after finding my work being sold by this seller I contacted the seller and asked him to remove my work. He removed my work, but asked why he wasn't able to use them as he paid for all the files on Shutterstock. I explained that you need to purchase a different license to sell merchandise with the designs.

Of course, Shutterstock doesn't care that someone is reselling thousands of pieces of art without the proper license and told me to contact eBay.
