What misunderstanding 

They are doing this for two reasons...

1) to receive merit for "high quality post"
2) to increase post count for signature campaign

...hoping no one will catch them.

- DO NOT copy/paste the entire article, even in quotes.  Doing that is stealing from the author since they cannot earn revenue off your plagiarism.
- DO copy just a portion of the article (less than 50%) and then post a link to the article so interested parties can visit the original site.

I like it! I've never used the quote-tag other than just clicking the quote button, but this works nicely.
Allow me to change your example so that the link is clickable by using the full link:
Or:

Real example:

Limitation: it doesn't work if the link is about twice as long as the one above.

I don't think I've ever posted much content from articles here, or anywhere else, but these guidelines are useful and make sense--I'll definitely keep them in mind if I ever need to reference an article.  

The real problem on bitcointalk with plagiarism as I see it is from people who are engaged in sig campagins and either can't write well or can't speak English well enough to post solid stuff that satisfy all the requirements of campaign managers.  From what I've seen (and reported to mods), they find an answer to a mega spam thread "question" and paste it into their own post here, and they thereby take all credit for it.  Plus they're getting paid for this.  There are certainly people copy/pasting entire articles, but I tend not to visit the press section or other sections where they must do it often.  I hear about it but have never seen it--but either way, it's wrong.

In some areas of the world, this sort of thing is accepted as proper.  These people need to realize that it's not cool to plagiarize on bitcointalk, though.  In the eyes of the forum, it's even worse than scamming (oddly enough).

Awwwww.

It might be a small percentage of people but, certain members will make this mistake and they get harshly called out because of the widespread abuse by other members. It does happen and it's only ever annoying when they continue to do so. The first time their post will be deleted and hopefully a friendly mod let's them know why it's been deleted.

It's obviously abused by certain members, but we shouldn't assume that everyone that doesn't quote/link to original article is doing so on the attempt to pass it off themselves.
