I wish Google would use a strategy that a former colleague used in an upper year Physics course. While encouraging students to discuss problems, he informed them that plagiarizing assignments was not allowed. When he got the first assignment, he noticed that the solution handed in by one of the top students in the department was identical to the one handed in by a much weaker student. So, he gave zero to the top student and full marks to the weaker student. (It should be noted that the contribution of each assignment towards the final grade was likely less than 2%). As he expected, the student who got zero went to see him. My colleague told him that he had no foolproof way to show that it was the other student that plagiarized the assignment and that the best method to prevent another zero being given was to not allow other students to plagiarize his assignment - if indeed this is what had happened. This solved the problem for that year ... and for many years after as word got around.<p>So... I wish Google would selectively remove links that are clearly submitted erroneously (claiming that, since the studios own these sites, no third party is claiming fair use) whereas preventing links where fair use appear clearly reasonable (such as wikipedia and reviews from news outlets) from being removed.
