It's an excuse to reply gibberish if you register hundreds of meaningless airdrops. They make you spam your twitter, facebook, some even scam in the process (like one that posted a pic on twitter that he was using their money to eat sushi). I sent donations to token that a worthless right now, bought some. And the thing is most of this people just come back under different usernames and start another airdrop thread. They just want to catch in money, just like the airdrop participants.
I even believe this forum is being spammed with token threads. Once I get some money, I'll stop their nonsense airdrops.
