Copyright and Plagiarism shouldn't be accepted anywhere, not only on Steemit! This argument is very dear to me. Someone just stole 57 videos from my youtube channel and created a duplicated channel with my face on it with all my content in it. THIEF.
I just wrote an article about it here.

Can someone advice me on how can I discover if people stole other videos?
