Yes, you can. PyBossa has a field for every Task named: calibration that will identify the task as a golden task or as we call them as a calibration task. Calibration tasks can be used to weight the answers of the volunteers (authenticated and anonymous) as you know the answer for those given tasks. For example, if a user has answered all the calibration tasks correctly you can give a weight of 1 point to all his/her answers, while if the user only answered 50% of them correctly, the answers for the rest of the tasks could be given a weight of 0.5 points.
