hi, everyone

    When I published an oTree project from Heroku to MTurk, I did not receive any responses from real participants, and if there were any, they likely were robots that entered the completion code and submitted without actually clicking on the link. To verify whether the issue was with my account, I posted a survey on MTurk's backend instead of Heroku, and received responses from real participants, which I then verified were not bots. So, where exactly is the problem?

and the only qualification I imposed is that the participants' IntegerValues should be GreaterThanOrEqualTo 500, so it shouldn't be a problem.
