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?
actually it can happen because you do not see the details of an airdrop that you follow, if doing what I do might be less likely to experience disappointment.
