Freelance Academic Writing: What's That?

I saw this ad on craiglist.org:

Freelance writers are responsible for taking available orders and completing them within a required deadline. Writers are given a login username and password to our website, ultius(dot)com, where they can pick up orders, track existing ones and communicate with both clients and administrators. As an independent contractor, you would be free to work on your own time. However, orders must be completed on time and according to exact instructions provided. 

My thought was: who is the market for this?  Organizations that need research projects done?  No.  As their website says: "Writing is painful."   They have samples of these ghost-written research papers for college students.  And yes, the papers are quite good.  So much for learning anything useful, such as how to write a research paper.
