Many person today are too greedy yet to lazy to spend even a little time to investigate at what they are getting into.
Also, sometimes, their greed is too strong that it clouds their judgement.
I am sure they are aware of scams - they're a lot of scams being circulated nowadays.
Scams are high risk high reward business. Scammers are most probably people who think that the only way they could make money is by stealing from other people.
For a minute I was admiring the sheer class and beauty of this scam, it was so nicely done, I was taken away by it, the length at which a scam can go might leave you asking questions like "for such brilliant minds, why not build something legit?"
I haven't seen the site/page but I am thinking that the scammer paid someone to make it this convincing.
