Received vouch copy from OP. I must say that method is not original. I've seen it all over internet. Statement: "The method goes in depth with details on what you need to do" is not really true since there are methods that aren't tested by OP. It requires investment and if you really want to make much money it would require too much work. This is read-only vouch, I haven't tested it but I think it should work if you just want to get some games for yourself. Also thing to be clarified, if you want to mass sell games, you would be selling accounts, not game keys !
