I think this is awesome because it helps students and they won't get in trouble for plagiarism. But i would have to agree that it is plagiarism because the student would be passing the assignment off as their own and it really isn't. But as a student with a job and rent and family and things to worry about, in a jam this would be amazing. Would I use it on every assignment? no. But If i  had 12 hours to do a paper and had nothing done I might consider it.
