The title of this thread is bit provocative, but the fact is that most people have a bad experience with airdrops. According to several airdrop hunters I spoke to, the majority ICOs don't pay out at all.
What's your experience with airdrops? Did you get scammed most of the times?
I have not been involved in airdrops for several months now because I do not see the point in this. You can now get a maximum of 3-5 $.
