The method is abusing the $100 USD free from google ads and advertise anything they want and bypass the google terms by clocking the landing page.
I hope that Google should remove the free $100 advertisement because this is the reason why we suffer about this kind of strategy that promotes a fake wallet in Google, Youtube and other Google ads partners.
Removing the $100 free add won't help because the hacker will just use some stolen CC's he buys off the dark-web. The amount of ad campaigns that are created everyday far outweights the amount of staff on hand in Google's fraud department to detect all these scams.
This is actually the reason why most Credit Card companies and Facebook ads have banned anything related to Crypto because there was just too much scam going around and it was a headache and they just removed them all together.
