Please post your questions about specific HITs, so I can respond here. Please include the full name of the HIT. Note: also posting HITs under requester name HI-Research. For HITs "Determine attributes of a person from an image": The task description clearly says: "Note: you can complete as many HITs as you like". Many people use this account, so others may have rejected HITs for different tasks. For the pictures that are of a book/record with the person's picture on it, it should count, because ultimately it's a picture of the actual person. Check full body for entire bodies only. The idea here is that a skeleton tracking algorithm could potentially determine where the limbs are. For a face in profile such as this, label "Part of face"
