I've had papers I've written a last year in my advanced composition class that came up suspiciously plagiarized, but I had the proper sites and sources to credit my own work and the instructor understood the type of research I had to work with. The damn paper was 26 pages long (ALL CONTENT), not counting the 6 pages of sources and cover page. I seriously doubted my ability to write that much content. I would hate for someone to take my own work and receive credit for it. So it's a good thing that plagiarism does stick with them through out their academic career. Shame on plagiarizers.
