Ghost writing is an interesting beast, which I say from the perspective of being a book editor by profession, and occasionally having been asked to ghostwrite things for people.
From the creator's perspective ghostwriters are sometimes important; lots of famous people with messages can't write their way out of a bag, so they hire ghostwriters who basically (most of the time) turn a jumble of ideas and spoken text on a recording device into something far more polished than stilted 7th grade English (or any other language). And generally, ghosting is a VERY well paid gig!
But that's a different scenario from the Steem environment where we are trying to build personal reputations as bloggers and content creators... or IS it?
I've only agreed to ghostwrite something for people twice in my 30-odd years of editing, and both cases were someone with a really good idea, but they were shit writers. So should their ideas go unseen by the world because they can't write? Each of those times, I made a judgment that they shouldn't.
The determining factor, however, was the nature of the content, however... if I had been approached with the idea "I need you to ghostwrite these articles for $5 each because then I can make lots of money," I would have declined.
If you have a worthy message but lack the skills to communicate it effectively, I'm OK with ghostwriting. If you're just looking to make a buck? Not so much.
