Where do I find airdrop items?

I'm curious, could you please elaborate on where one might find airdrop items in the world of cryptocurrency? Are there specific platforms or websites that are known to distribute these tokens? Also, what kind of precautions should one take when participating in airdrops to ensure the safety of their digital assets? Lastly, are there any red flags to watch out for that could indicate a potential scam? Thank you for your time and insight.
