I was wondering how the school know who did it. If it is merely based on whose name was access, then is it not possible for a person to sabotage another "competitor."
I think it is bit of a leap to claim that these people will be committing plagiarism. Personally I never really understand the need to plagiarise. Basing your essay on one work without citing the original makes one guilty of plagiarism. Taking a large number of other papers and using them in your work while citing them somehow makes you a hardworking researcher and invariably gets you an "A." I recall once in college when writing a paper in which I had ZERO original thought and all I did was cite others, resulting in footnotes/endnotes being as long as the paper and I got an "A" with a praise of doing GREAT research.
