Turns out, there aren't.
However, I DID come across this particular "job" posting.
|Hello I am in search of good and professional writers who are exceptionally good at writing content and meeting deadlines. I need unique and quality content that must pass Copyscape filter. Successful candidates will get a long term position in my company. I will pay 1$ inclusive of oDesk fees for 500 words article. I need at least 5 articles per day. Serious bidders only.

Cheers to the rest of the week!
