These days, services like Turnitin are good at catching plagiarists within minutes of scanning their content, but some people still don't get it. Oh well... such is life.

Totally agree with this. I used to teach at university. We had an honor code and council to deal w/ plagiarism - its a big deal if you ask me (and really offensive to the instructors and asshole-ish to the authors/scholars). On more than one occasion I have though about how the digital currency ecosystem could use its own honor code/set of standards notwithstanding whatever laws and regulations are also applicable to the industry.
