Airdrop in the crypto space has evolved from doing extremely simple tasks like posting on social media to doing more complicated tasks in testnets that are common nowadays. Honestly, I stopped doing airdrop hunting a long time ago, but I don't expect that we need to spend money now to get airdrops, and it's still not sure that we'll get them. It makes me avoid airdrops more unless they're airdrops, as the effect of using previous popular chains like Ethereum, Stellar, etc. makes me think it's really risky.
