Why can't i get airdrops?

I've been hearing a lot about airdrops in the cryptocurrency world, but somehow I never seem to be eligible for any. Could you explain why I can't get airdrops? Is it because I'm not active enough in the crypto community? Or do I need to meet certain criteria to be eligible? Also, is there anything I can do to increase my chances of receiving airdrops in the future? It seems like a great way to acquire tokens, so I'm quite eager to learn more about it.
