That's why I'm not the fond of airdrops. I firmly believe that bounty is better as they worked hard for it and have them harder to let go of their tokens.
I agree , only hard work should be rewarded and multiple account creators are nothing better than spammers.
I think that there will be no airdrops soon. Too many scam coins/tokens. Just for e-mail and telegram base collection.
There were some great projects that were destributed by airdrop, but that is really small quantity among all.
All good things cant be destributed for free, you need to pay for them
