I don't nag it, I just don't like copying. On arts that is done like that in the past, like Mona lisa, it's meant to be that exact person or place, so then ofc refs is required and they pose to be painted. In all, the poser agrees to be painted. I think that copying a reference you find on the internet, especially if it's of a person, is as bad as stealing the picture. as the person on the photo or the owner of the original picture have not agreed on you drawing it. However if you only use the anatomy or the base of the objects or surroundings, you do not copy the art and therefore make it more original and own as well as not stealing something you do not own the rights of. No matter what you say, I will only use references to see the base and anatomy unless it's a person I'm about to draw and got the rights to draw them. Though even then, I'll change the pose and clothing (as for the draw an mt member thread).
