I would report it and let the Mods decide. I think it's just another way for these copy/pasters to try and see how close they can go to the line before getting banned. I assume they are just trying to make the article appear as if they wrote it, but that they used the reference for source materials.
Personally I'd include members who do this with a proper source. It's just another way to boost their post count; and they are to lazy to try and write a post with a link to the site or provide anything of value.
The right way to do it is to provide a link to the exact page the quote comes from. This should be obvious, but who knows what level of education this knucklehead has, not to mention where his moral compass points.
I'm going to assume if the guy can copy past an article, they should be able to copy the address bar. Like I said above it's like a toddler testing to see how far they can go before a "timeout". These "earners" are just seeing how close they can get to the illusion of well written creative posts, without doing any work and avoiding punishment.
