This is the question that is currently un-answered. The response "Exclusively for me." is suggesting that the author provided calidos with the article for his consumption, and the author was unaware it would be reproduced for profit on steemit.

If he's purchased the article and written exclusively for him then he has the rights to it and can use it where he wants. If he's only used it here then this shouldn't be an issue. As I've seen plenty of times. If he uses it on another site where he owns access to like a blog he just needs to post on there indicating that he also posts on Steemit to show he's the owner of the other property.

there is one other question that comes to mind here.. if this was written for you, how did anyone even know the difference? did some of the content show up elsewhere?

This has been answered plenty times man, I purchased the article and all the rights to the article. If I purchased the rights to the article that means I can do what I want with it. Does not matter what I do with it because its mine full rights. All rights from the author are given up because I purchased them. How more clear do you want me to be?
