Well, I will agree with you that this seems to be getting redundant so maybe we should cut it loss. But it is statements such as:

“I sometimes credit model sources & sometimes don't. It depends on how prominent the model is in the overall composition…”

“I don't feel I'm morally obligated to credit every model I use every time. It would also be a tedious task to keep track of the models I use in each composition - I view creating art as play & that would make it more like work.”

"That said, I do periodically credit modelers whose work has become an important input to my own..."

That glares out and beckons discussion.
