Copyright is a serious thing, if you really love what you do, you will stand up to defend your rights.
I also had a copyright problem once.
You have very good jobs.
I tried many times, but apparently it's not mine.
But for that I photograph well.
The most important thing for me as a photographer is to protect my work from intruders who want to use my work without my agreement.
If you, like me, are afraid of such scammers, then I highly recommend you to use this application https://play.google.com/store/apps/details?id=com.visualwatermark.watermarkly.
Especially if you are putting photos of your work for sale, or just on the Internet.
Take care of your safety.
