Ah, plagiarism. Sometimes you just have sigh and wonder why they just don’t do the work.  Would you really want to employ someone who went to these lengths to get out of a deadline?

“Most of us have had the experience of receiving e-mail with an attachment, trying to open the attachment, and finding a corrupted file that won’t open. That concept is at the root of a new Web site advertising itself (perhaps serious only in part) as the new way for students to get extra time to finish their assignments.”

One obvious way around is to mandate the submission of the file to the organisations plagiarism software prior to handing any work in.  As well as checking for plagiarism, it will only work with a functioning file.  All corrupt files would be then treated as suspect and then checked with software that lets you look inside the corrupted file to see if it is genuine.

Sigh.
