Problems on Steemit!

I posted some articles on my Reddit account. I posted same articles on my Steemit account.
Now, the bots here on steemit has blacklisted some of my posts because of plagiarism. Wtf?
.
Those are my posts on both the places. I can post it wherever I want. Where can I file dispute about that?

Edit: Just now I posted a news article, I gave the link as the source. Still, cheetah came on my post!
