    Hi all,
    I'm a newbie in MTurk, really need your help. I have an online experiment with 8 conditions (i.e., 8 HITs), and I want to avoid worker who has accepted one of my HITs to do any other HITs, or to retake the same HIT. Is that possible? How to do that?

    You can use qualifications to put workers into groups and allow them to only access HITs within that group. Here are two posts from MTurk about using qualifications:

    Here are other ways to fairly prevent retakes:
