Hm. If it's tracing some parts and drawing the rest in themselves, there may even be some people who don't see it as stealing at all. Their mind may not even just be in stealing.
They may say 'Oh, hey! That person is an amazing artist, I should see if I can learn a thing or two from their style!
And that's all where their mind may be. Not anywhere in 'Oh, if I did that it might be stealing.'

Because honestly, if I try to think about myself doing that, stealing would be the last thing on my mind if I draw something , and it turns out well, and I want to hear praise and critique. XD I dunno.
Everyones different. :3 And we all make mistakes. x3

But for those that are doing it with 'I'm stealing this' actually on their mind, then yeah, they are pretty much to blame. They're doing it intentionally.
