To add to the evidence you provided, if you look up their eth address on etherscan.io you will get the following warning message: "Warning! There are reports that this address was used in a Phishing scam. Please exercise caution when interacting with this address." So, no doubt that this is a scam.
This, at least, proves that reporting scams is not useless or a waste of time as some may think.
Other than reporting the fake website to google, we can also report it to the domain registrar (Sav.com) and to the hosting company.
these warning on blockchain appears later my accusations, at least now it's has been clearly identified as a scam.
when I have created this thread there was nothing suggesting a scam (that's the reason I have posted immediately here on forum).
I guess it was just launched when I made the thread since there was just a comment in coinmarketcap "live chat" and now has been deleted.
