Maybe you're doing signature or twitter or fb camp? It depends on the bounty or airdrop you're doing. My definition of hardwork doesn't mean that you're working for 24hrs, for me its about the effort you exerted. For example you are doing a blog bounty. It will cost you an effort so that you complete the task. Even you've done it for less that 5 minutes, you still made an effort just to complete the task.
