The whole point of MTurk is to get data you will use to train your models. Using some artificial means to make money on MTurk would be circular, and probably easily spotted - if not, your model has effectively solved the problem domain anyway!

We do language related things on MTurk (crowdsourced translation, for example). It's very easy to spot those who have used something like google translate or other artificial means - it's quite rare for a sentence to be translated exactly the same way twice, for starters.
