I have just found one of my shirt designs stolen and listed for sale on a third party Shopify store:
My design has only sold about three shirts since I put it up, so they must be stealing loads of shirts, even ones that are not best sellers. Check to see if yours is on there!
I want to report an infringement to Shopify, but do I have to provide my phone and address? I don't really want them to provide my address to the thief.
