Volunteered for a flight, but was not given the documents to sign until the jet bridge was pulled and the plane was gone. The compensation was 400, so no complaints, but I wonder if some unscrupulous person could say that's not enough and not sign the documents until the agent raised the comp, threatening to force an IDB if they did not. In the DOT's eyes/ legally is it only agreed to when you've signed on the dotted line? Or does clicking yes on the kiosk count as an agreement? Debate...
