Thanks everyone, I have replied the ticket. But so far no one relies the ticket.
I saw other people posts same article rewrite and it is not taken down ?
It is not a violation to have articles re-written which you own (have written yourself or have hired someone to write)
It is not only a violation of Upwork's terms of service, but also illegal, to rewrite (or have rewritten,) articles that you do not own the copyright for.
