Very interesting, I've been using Mechanical Turk to help compile some business listings -- my first time using the service in a number of years. I decided to review some requests made by other people, to better understand how to write my requests. I'm amazed at the amount of affiliate fraud! There are tons of offers paying people to fill out a form via an affiliate URL. There are even lots of examples of more advanced fraud where they give the person a script to read from, when the lead gen companies calls about the form that was just filled out......and even more complex schemes.
A most interesting service would be one that grabbed every URL in every MTURK job request (called a HIT), followed the URL to its end destination URL (as most go through redirects and/or shortning services), and then provided to affiliate companies this list of URLs, that were posted in an attempt to generate illegitimate leads.
Doesn't seem like that tough of a scrape, right now I see 180 pages of requests, 7 requests per page, I don't think amazon would shut down a scrape of 1260 or so pages per day if done smartly.
