Methinks thou doth profit too much?

Of all the reasons to get canned, hyperproductivity seems the most cruel.  From MTurkforum.com:

I'm a new turker, but knew something about it because my daughter is a turker.I did about 2,000 hits in a week, 99% approval rating, they suspended me without ANY contact from them, I've written them 3 times. Only answer is automated email. After reading this forum, i'm thinking that my number of hits led them to believe that i was using a robot or something. What a ripoff, with no way to resolve, complain or have any recourse. Worse than a slave. Hope you have better luck, but beware.  link
