Using mTurk to Find Common Errors

Steve Tse has put up a few typing HIT's which have a really unique idea to them. They simply ask a Turker to type the same word thirty times, not correcting any errors typing or spelling mistakes. This could be used for finding domains to register for spelling/typing mistakes, creating redirection directories, finding cheap AdSense ads for misspelled searches and tons of other stuff that AI can't quite figure out how we manage to mess up in the way we do.

Now here's the issue, at least 97% of Turkers are good people who are just trying to make some extra cash during their free times, but there are a few bad apples. A script could pretty easily be written making a person only have to type the word once, and then it just copies it. Or there's good old copy and paste. So how does one keep Turkers from cheating? Shoot all that you catch cheating with a rifle, but illegal scare tactics tend to be troublesome. What one could do is use some sort of JavaScript to keep boxes from being pasted into, but I'm sure a GreaseMonkey script could get around that. So the real solution is um...I'll get back to you on that one.
