For about 8 years i am selling stockphotos, and now i ve discovered Google image search.
Often i see people selling my photos, mostly on sites difficult to translate
Problem is i can not translate anything to take any further steps.
Yesterday i found a photo from my here:

https://www.etsy.com/nl/shop/huayiphoto?page=1

I signed in on that site, an ask them to remove it and they did.
Mayby there are some of your photos out there.
What is your experience ?
