Speaking with customers and being one myself being able to exclude specific shops ect from the marketplace search would be amazing. This would be helpful for customers to be able make copybot marketers no longer visible to them as well as shops they may find offensive aiding them in a more pleasing experience on the marketplace and their/our searches more productive.
Just curious... Why do you make your items no copy? Making them no mod, no trans would easily solve that problem and is almost always acceptable per content creators TOS. Customers might appreciate that more as well. Some things people like to save a boxed back up copy in case of accidental deletion ect. ♥
