As soon as you enter the twitter account then you can see hundreds of airdrop posts in front of you where there are promises to give many tokens for free. Do you think all these airdrops are true? I think all are false and from here there will be possibility of hacking to connect your personal wallet. So be careful and avoid fake/false airdrop.
You are right though, but then, we can't actually say that all the airdrops that are being posted on Twitter are all fake airdrops, some of them are actually genuine, but it's a very minimal percentage when compared to the percentage of the fake ones, and you also may want to know that some this airdrops arent actually a way to steal from unsuspecting participants, but some are actually launched as a way of farming engagement and as well gaining followers.
In crypto, we have alot of airdrop hunters who do nothing other than hunting from one airdrop to another, personally though, I wonder how this people make money from all this, but I guess they must really be some special kind of people in terms of having or being patient.
Anyways, for us that are here, it's still a very good advice for us to try as much as possible to avoid engaging in airdrops we are not sure if it's genuine or not, most especially those that require us to connect our wallet to some dapp and sign a transaction, we need to be extremely careful so as never for fall victim to any of such scams.
