The painful part of my airdrop journey is that the one I should have made at least $100 from is $BR, but I was not eligible when I checked.
I also experienced that on two airdrops that I participated in, and this is because I missed to abide by their rules of upgrading my account, so I was left out of the airdrop. Even if it's an airdrop, be sure to follow the qualification rules. airdrops is far different from the airdrops 7 or 8 years ago; they can set their own rules even if its a strict rule because they know that many will still participate, even if the rules are harsh.
