Why can't I receive airdrops?

Hello, fellow crypto enthusiasts. I'm a long-time investor in the cryptocurrency market, but recently I've been encountering a puzzling issue. Despite my best efforts to participate in various airdrop campaigns, I seem to be unable to receive any of the promised tokens. I've double-checked my wallet addresses, followed all the instructions, and yet I still end up empty-handed. Could you possibly shed some light on why this might be happening? Are there any common pitfalls or mistakes that investors tend to make when trying to claim airdrops? I'd greatly appreciate any insights or advice you could offer on this matter.
