Airdrop is not a thing anymore. I guess. Haven't joined for so long as well. Because it is not worth your time and effort. Usually, the gas fee or withdrawal fee is higher than the actual amount you will get. And you need to wait for them to credit on your wallet and sometimes you already forgot that you participated because of the long timeframe of joining and sending the tokens. But still, there are individuals who try their luck to get freebies.
