Is a pretty interesting look at the world of custom paper writing. Working doing the college papers of other people who suck too badly to write the papers themselves. A few things stick out about the practice. Not plagiarism which is mostly detectable, but getting an actual paper that nobody previously wrote.
The subject matter, the grade level, the college, the course—these things are irrelevant to me. Prices are determined per page and are based on how long I have to complete the assignment. As long as it doesn't require me to do any math or video-documented animal husbandry, I will write anything.
No math. You can't fake math.
After I've gathered my sources, I pull out usable quotes, cite them, and distribute them among the sections of the assignment. Over the years, I've refined ways of stretching papers. I can write a four-word sentence in 40 words. Just give me one phrase of quotable text, and I'll produce two pages of ponderous explanation. I can say in 10 pages what most normal people could say in a paragraph.
Density. You end up with huge pages of ponderous drivel where reasonable ways of saying things just doesn't take up enough space.
... and the obligatory xkcd.
