YOU MUST STATE IN THE ARTIST COMMENT AREA THAT IT IS UNRESTRICTED STOCK !!!!! If your submission was denied, this is the main reason why!
This is a request from the group founder. There is no way around it. If you can reword it so many different ways, please add the word "Unrestricted" in your artist comment area. If "unrestricted" is not in the artist comment area, your submission will be declined. "Free" "free to use" etc... that means there is no charge for use. The loophole is if someone uses stock marked as such commercially, the stock artist may seek amends at some point. Just please use "unrestricted" if that is your intent.
