I was roaming around one of the art sites and came across a page where the young artist was saying “I’ve had enough of this! Every week I get news that my work is being used without my permission in articles and on sites, or being sold, etc, and I’m just fed up with it. I’m going to pull all my pictures off and leave.”
One of his friends came along and said “wait a minute, please think about this first… if you go, leaving all your pictures out there, nobody will know who created them. But if you stay long enough, people will get to know.”
That is true… and the ones who didn’t make them usually give themselves away, one way or another.
