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?
Nowadays there are lot of ICO whose offering airdrops for all the people who wants to join but as I observed there are many airdrops tends to become fake and scam afterwards and that is the fact that we cannot hold. I, myself also experienced to join a bogus and scam airdrops but after that I make myself sure that everytime I join an airdrop it should be legit and reliable.
