First, I would like to clarify that I am not in any way siding with the "fraudulent dimwits" who have recently flooded this message board with horrendously substandard writing.
Second, I also agree that not all students use the papers that they buy as is. Some do paraphrase and others do rewrite some of the content to integrate their style. I know because I have such clients. However, I still find it hard to believe that any student would properly site the source of a purchased paper. I think that any professor would raise an eyebrow at reading that one of the sources that a student used was purchased from an essay mill.
Nevertheless, I do believe that a great majority of students do submit purchased papers for credit. Whether this is right or wrong is none of my business. I only write the papers and have no control as to how they are used.
Of the eight (8) BU students found to have purchased papers, seven (7) of them referenced the sample papers properly
1. While this evidence did exonerate the essay mill, it is statistically invalid to infer that only 1 out of every 8 students submit papers that they buy for academic credit. Please, not your "general statistics" again... >.<
2. Even if we assume that only 1 out of 8 students submit purchased papers as their own, it's still a significant enough number for academic institutions to be concerned. If there were 800,000 students who were clients of company X, a 1:8 ratio would mean that about 100,000 of them cheated their way through college.
