Similar thing happened to me about a year ago, I was relentlessly searching for airdrops everywhere I could find it on the internet when I've actually not even read about what airdrop means. I also participated in some airdrops on telegram using telegram boot, which all turned out to be fake. It's just best that one should study well about a project before embarking participating in the airdrop and if all test proves it to be scam, one should just shut the thought to participate in it off, regardless of how attracting the worth of the airdrop is.
And these airdrops are becoming gateways of collecting information of the participants. When the participants are intrigue with the project, they're like blind followers that would do anything the airdrop developers are going to say. Like providing those details, email, ids, I've seen some that do really required it and their reasoning is to avoid cheaters that do claim twice. And in return of that, they'll take those information and have it saved on their databases and you'll be surprised that you'll be receiving spams in your email.
It means that we should not give our trust easily to those new projects or their raindrop. Cause nowadays scammer is always on our side we need to be vigilant to prevent any kind of loss. Because scammer try their best to convenience you to participate in their project but in the end of the day they will leave you in the air empty-handed cause they took all your money. And in addition, it's better to find a regular job than airdrop hunting.
