Of course they fall into this trap because they are greedy, lack knowledge and don't look for information first when getting an airdrop link or something like that which requires us to connect a wallet or have to follow the airdrop.
Honestly, every day I get airdrop invitations on Telegram, but I don't care, I just block them. That's the best way we can do it because there is no free airdrop without being given a task. I'm not saying all airdrops are scams, there are also airdrops that make more money like tesnet and running its project nodes.
The lack of common sense of greedy people is incomprehensible for those that are not dazzled by it, as instead of wondering why would anyone share that amount of money with them and become suspicious about such an offer, those people get happy due to the sudden opportunity that came knocking on their door and they rush as fast as possible to take advantage of it, and in their hurry they are bound to make many mistakes that scammers can then use to their advantage.
