The consensus on Steemit is to choose the option of "Decline Payment" (instead of 'power up' or '50/50') if you are posting work that is not your own. The problem lies in getting paid for someone else's work. It is considered a form of plagiarism here so things are much different than they are on Facebook where you can share whatever you want because you don't get paid.

I'm just explaining and not attacking ... I came here because I wanted to see if you were unjustly flagged so that I could possibly counter it for you.)
