I really find it hard to believe that Crowdflower truly cares about the "integrity of the data" when they continue to make it difficult for the workers to do the tasks well.

In fact, I'll go so far as to say they DON'T CARE about the data.  Not. One. Bit.

Ya hear that, Oh Mighty TAs?  THEY DON'T CARE ABOUT YOUR PRECIOUS DATA!

All they care about is attracting more TAs, and if they have to crush the souls of the workers to do that, then so be it.

But remember this - if Crowdflower continues to lie and hide things from the workers, what are they hiding from YOU, the TAs?  And what lies are they telling YOU?  Can you really trust the data you are getting?  I'm thinking the answer to that is a big fat NEGATORY.

Think about it.
