Gullible people will always fall for things like this, i know it is easier for people to fall for this type of scam because of the account it was posted from, but we have learnt from the past that the accounts of companies and prominent people have been hacked and used to scam quite a lot of people. So do not easily believe all posts about airdrops or giveaway, notwithstanding the account it is coming from.
This is exactly where the problem starts, and that’s the reason why most of these influencers accounts are being attacked and hacked: people are too ignorant about things, and whatever they see posted on their influencers official page doesn’t need to be investigated or doubted; rather, they should act as urgently as possible in order to take part in whatever the link promises them.
Sometimes the kind of link that these scammers or hackers use to promote something is something that, in a normal sense, the original account owner won't share on his or her page, but greed and ignorance always make those newbies fall prey to such scams.
