Looks like this has happened before. This thread about it has the IRB information. Make sure you include the link that shows how to reverse a hit. Show them the participation agreement that states "3. Your Use of the Site. (vi) you will not reject Tasks performed by Workers without good cause " I checked their IRB website and the consent form template they ask requesters to use says this. "2. If the study will pay participants, please indicate how much will be paid; otherwise delete. (For example: If you agree to take part in this research study, we will pay you ________ for your time and effort.) Be sure to indicate if the amount is pro-rated by research visit or research procedure." You could send something to the IRB that states that since you did not get payment for your data, you do not want it used. Hopefully this will force a reversal, because it looks like they rejected a lot of people. The IRB could render that data useless.

Question - Why hasn't anyone reported their rejections on TV or TO2?

For reference here is TO1 showing a ton of reviews, but not everyone uses just TO1.
