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.
Corrupted-Files.com offers a service — recently noted by several academic bloggers who have expressed concern — that sells students (for only $3.95, soon to go up to $5.95) intentionally corrupted files. Why buy a corrupted file? Here’s what the site says: “Step 1: After purchasing a file, rename the file e.g. Mike_Final-Paper. Step 2: E-mail the file to your professor along with your ‘here’s my assignment’ e-mail. Step 3: It will take your professor several hours if not days to notice your file is ‘unfortunately’ corrupted. Use the time this website just bought you wisely and finish that paper!!!”
