please. Help me and my friend.
One of my freinds is Nojagyu(노자규).
His job is web-essay writer. So his works have copyright.
But recently he got an infrengemnet of copyright against his works.
He dosen't have any Steemit ID and even dosent' know about it.

one steemit ID @steemitkorea seems to act like him.
That ID posts his some works and replies even get lots of dollars.
What can my friend do to handle the copyright infringement?

please check it in detail and sincerely..

thanks for reading my post.
