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.
I've seen people getting happy after receiving such offers when they have newly started using the internet or maybe after getting involved with stuff like online earning or cryptocurrencies, etc. The reason is that they are too naïve to understand and lack basic knowledge about how things work, their mindsets are different in the beginning because they always hear people saying that they have made a lot of money from cryptocurrencies and they have this image in their mind that cryptocurrencies can make someone rich overnight.
I was once a newbie, all of us were, and I don't blame them for any of that, a newbie in a new industry is like a child who knows nothing and will believe or do anything that they are asked to do because they think it is going to do something good for them instead of thinking critically about the situation.
