Ask yourself: are you producing the entire article for some motive, reason or purpose beyond further dissemination of the article?
Are you in any way, shape, form or fashion harming the author(s) of the article?
Are there posted restrictions on the dissemination of the article which would be violated by reproducing the entire article on this site or any other?
If not, go take a nap and stop worrying.
By the way, erstwhile writer, my editor would have a field day with you. There is no such thing as being "perfectly legal" any more than there is a condition of being "partially pregnant".
