Backlinks from MTurk?

I have been using microworkers to get blog posts and blogroll links and have had some very good results doing this over the past couple of months, but it seems like I have pretty much tapped out the users because I keep getting the same people over and over now.

It looks like doing this same thing in MTurk is against their policies and will get my account banned. I'm sure several people here have tried this on MTurk, what was your experience?

Are there any other sites out there (besides the ones listed below) that have a large user base to get these kind of links? I have tried these sites below and most of them just seem to have so few users that I get no results. I have had such good results from microworkers that I would really like to find a couple other similar sites.

jobboy
simpleworkers
desklancer
minute-jobs
shorttask
microjob
tasksworkers
minuteworkers
rapidworkers
jobby
myeasytask
minijobz
whatask
livework

I've tried many places as well, and Microworkers is the only one that has been good to me . . .

When they get really tired of closing your accounts a lot they blacklist your last name, address, all kinds of crap so you have to borrow someones CC But ya I used to outsource them some people do it well and some people are morons but given specific enough instructions they can do any task.

The other good site I know of is Odesk but its like longer term stuff, if you can find someone good and get them to do a larger project it works well.
