thank you for the info, but why is this so hard for people to understand. I understand that newbees might fall for this but then the sighs are everywhere.
Because unless you have read a thread like this, then newbies often fall for this, as you said. Remember that these newbies often learn about airdrops and "free money" before they learn about public keys and private keys, namely giving out the former and securing the latter.
This sticky isn't for seasoned airdrop participants who know better, it's for those who are new.
