How to get a free Solana airdrop?

I've been hearing about Solana's recent airdrop promotions and am curious about how one can actually get a free Solana airdrop. Could you please elaborate on the steps involved in acquiring one of these airdrops? I understand that it's typically a reward for early supporters or participants in certain projects, but what are the specific requirements or actions needed to qualify? Are there any caveats or risks associated with these airdrops that I should be aware of? As a crypto enthusiast, I'm keen to explore these opportunities, but also want to ensure I'm making informed decisions.
