I was not aware airdrops had turned into something more than the lowest-level social spam giveaways. Thanks for letting me know. Needing to invest real money to qualify for an airdrop seems like a big upgrade, too bad it didn't choose a fresh, new name instead of "Airdrop."
They don't want to change the term because the word airdrop is attractive to new and old investors even if the structure from the time I first encountered airdrop here, it is very different now, the new airdrop term in the Crypto community is doing task and staking coins into your wallet.
It now involves effort and money so always check the airdrop that you're going to participate with so your money and effort will not be wasted, there's always risks involved in these airdrops.
