Did you not read any of it? Just check his deviant art.
What Scriptor does is exactly the same thing other artists do. He adds to favorites those images that he likes and that serve as ideas for his future work.
Here no one has invented anything, and everyone copies others to a greater or lesser extent, contributing their style.
If you look at the profiles of the artists that Scriptor has in favorites, you will see that they also have saved images that are similar (ideas) to many of their own works. It's normal.
Do you want to know what's really pathetic? The contemptuous treatment you are giving to a developer as if he had committed a crime.
Honestly, I think you should relax a little, because you're dramatizing so much that it's embarrassing.
