I think it's great of FC to give a larger compensation, when you have spent a lot of time on a survey and still get disqualified. It helps take the sting out of the situation. That has happened several times for me. It's when you get bumped at the end of a long survey, and get no compensation at all that frustration sets in. I had a long one last night, and at the end was required to answer a question with a video from my webcam. I managed to finish the video, and upload it with an upload button but then the screen went black and I didn't have a clue if I had done it right. I never got my reward, so guess I didn't do it correctly. I'll go with "practice makes perfect" and get it right next time!
