How are people this dumb

I clicked on a youtube live stream thinking it was legitimate Ethereum content. Come to my surprise it's just a front for this common "ETH doubling" scam. I looked at the etherscan for the listed address, and sure enough, they've managed to accumulated 11 ethereum in the last 2 hours.
