What is your reasoning behind such a statement? Did you even think for a second before posting something so silly? I agree that majority of the airdrops are indeed scams, but there are airdrops like NEM, Decred, DeepOnion etc that have rewarded people with a lot of free money for just signing up for their airdrop. I am talking about thousands of dollars. DeepOnion actually made many people happy by giving them free money on a regular basis(2 of my friends can attest to this) and people still call it a scam. They have the right to change their rules whenever they want to.
