The airdrop / project feature is prone to scam:

1. They provide the conditions to send some eth to their address to get a token (This is clear, why do I have to pay for the dropdrop?)
2. When filling out the form, you are asked to fill in the private key (It is very clear a scam, because if they know your private key, you can "your wallet balance is sold out)
3. The website is suspicious / suspected of phishing (they usually ask you to fill in the data "private" on their phishing web)

Hopefully it can be a lesson for all of us, to always be careful "in following the airdrop Smiley
