So, is the wording wrong on the steemit.com website then? See the link above.

I think it is common to claim more than copyright law actually protects. Patent law can protect "look & feel" but copyright is pretty limited in this respect.
Did an expert copyright lawyer actually look at this clause or did they just copy it from somewhere else?

Of that I have no idea. Just been going off of what I can find doing a few google searches and steemit searches.
