But bad thing is people still depositing on that scammer address. How greedy people are even they can't determine direct scam. Scammers are spreading their script link via social media like Telegram, Twitter, YouTube and so on.
Maybe the scammer is doing transactions from his addresses to show that people are trusting this site and are applying for the airdrop. It's not that hard actually.
It's a good thing that you are placing a warning but most of us already know that an airdrop asking for deposit is a big red flag.
That looks like a scheme used by Bitcoin doubler scams. Now scammers are creating FAKE EXCHANGES with very attractive rates. Be careful!!
Perhaps a blog/or an EDU thread about this and how to spot sites being operated by scammers should be good and helpful for newbies.
