I am a seasoned designer and have proof for all my ORIGINAL art and everything I submit is in fact my original work. Within minutes last night after uploading my design I received a rejection email on my pop socket design accusing me that I uploaded a copyright violation. I have NEVER submitted in my years of design a plagiarized design or been accused of copyright violation as you have done!! Excuse me?!
WITH ALL THE WORK IT TAKES TO UPLOAD OUR DESIGNS, THEN YOU require us to fill out an email proof in order to resubmit. Are you just sending a form letter to every designer that is anything other than just text? Or do you have someone (or not) who doesn't know how to check for copyright infringement and just making assumptions first?
What really angers me is that I read many posts on this forum that admin is not protecting our designs from the very thing you are accusing us of. So you question us for copyright violation BEFORE you ask for proof and on the other hand you take no measures to protect the designers here?
I suspect you can't service your designers because you grew too quickly. The same problem that happened with Kindle and CreateSpace. But they finally got if figured out and now have quick "live" representative help that we expect. Maybe you need to ask Amazon to help you since you are not affiliated with them even though you use their name on your logo.
Sorry for the harshness, but most seasoned business people expect more in service that can be found these days.
