Well I read his method and it would work, but I have some concerns with it. I Personally would not use this method, but I am sure plenty of people would be willing to. The simple answer is: Yes it would work (I know some people that do something similar), but comes with some risks for sure. OP is not trying to scam anyone by selling this, but it is for sure in the grey area.... Not really sure how else to describe it without leaking parts of it. If you do this method use your head while doing it and avoid the obvious issues it can cause.

Sorry for not giving a clear cut answer, but this is all I can really say about it. If you do not mind being a little risky you can profit. I do not venture into the grey areas so this is not for me.
