I have submitted two shirt designs using my own artwork. They are associated with my own youtube channel with less than 10k subscribers. There are no parody type slogans that mimic any pop culture or anything that should be risky for copyright.
The designs are being rejected. When I send a dispute email I get a response in 24 hours from a bot saying I need a letter from the copyright owner and their contact info. I did include the Email address used in my youtube account and my phone number. I don't know how to get Amazon to realize these are my designs. Anyone seen this before?
